For Caps Lock mode, pressing and releasing the lock key turns on the mode and pressing and releasing the lock key again turns off the mode. In Shift Lock mode, all keys on the main keypad send their shifted character when pressed alone. For Shift Lock mode, pressing and releasing the Lock key turns on the mode, and pressing and releasing either the Lock or the Shift key turns off the mode. --- need timeout on CXWindowsClipboard::CReply objects should flush replies that are too old assumption is that requestor is broken --- avoid fullscreen transparent window on win32 using CBT hook to discard activation/focus messages but it's not being called when we lose keyboard input also, we sometimes don't get the keyboard input to start with --- keyboard hook problems (win32) now passing keyboard events through in most cases this fixes problem on isabel where toggle lights don't toggle and num-lock behaved incorrectly (generated wrong keys). seems the DefWindowProc() needed to process the keys unfortunately, keys sometimes leak into wrong app. seems related to times when we don't get the keyboard input. key events are not delivered to app on primary until cursor returns to primary. no idea how that's possible. current have some code to check active window and reset it in keyboard hook. that code doesn't work. seem to be having problems with windows key now, too. looks like a down is sent but not the corresponding up so secondary system thinks the key is always down. --- key events sent to console on win me (95/98?) are very slow 1/4 to 1/2 second delay before key up is processed key up log message is also delayed console causing a system-wide delay? --- adjust thread priorities on win32 maybe remove changes altogether currently isabel starts single-stepping mouse when dragging window sometimes it goes normal speed but it's mostly very slow even a very high priority doesn't seem to help haven't tried real-time priority a very high priority on client fixes delay when typeing into console is it the output console causing the slowness? mouse motion compression seems to handle slow dragging on grace pretty sure nothing else was wrong on grace maybe same problem and solution on win32 --- results: X primary ctrl+alt+keypad_add, ctrl+alt_keypad_minus -> eaten by primary X server ctrl+alt+backspace probably eaten by primary X server if so configured ctrl+alt+delete probably eaten locally probably underneath primary X server too Win32 desktop -> X laptop eaten global hot keys: ctrl+alt+delete -> task manager (or logon or reboot) alt+[shift+]tab -> cycle through tasks alt+[shift+]esc -> cycle windows ctrl+esc -> start menu windows+R -> run dialog windows+M -> minimize all windows+shift+M -> undo minimize all windows+F1 -> help windows+E -> explorer windows+F -> find files windows+ctrl+F -> find computer windows+tab -> cycle through taskbar buttons windows+break -> system properties not eaten: alt+space -> system menu shift+F10 -> context menu app key -> context menu misc: accessibility shortcuts: not eaten but dialogs appear anyway X laptop -> Win32 desktop check: shift+tab -> okay alt+[shift+]tab -> okay alt+[shift+]esc -> okay ctrl+esc -> start menu -> okay ctrl+esc, esc, shift+F10 -> toolbar context menu -> okay F10 -> activate menu in explorer -> okay shift+F10 -> context menu -> okay alt+space -> context menu -> okay alt+hyphen -> MDI window menu -> okay alt+letter -> open corresponding menu -> okay alt+F6 -> switch between windows in single program -> okay shift+insert CD-ROM -> bypass auto-run check accessibility shortcuts -> does not work check accessibility features sticky keys -> no filter keys -> no toggle keys -> no mouse keys -> no high contrast -> no X desktop -> win32 check: shift+tab windows+R -> run dialog windows+M -> minimize all windows+shift+M -> minimize all windows+F1 -> help windows+E -> explorer windows+F -> find files windows+ctrl+F -> find computer windows+tab -> cycle through taskbar buttons windows+break -> system properties app key -> context menu Win32 -> Win32 alt+F6 -> eaten (isabel to audrey, but not audrey to isabel) check accessibility shortcuts work on secondary check accessibility features work on secondary --- Accessibility Shortcuts Key Result ------------------------------------------------------------------- Tap SHIFT 5 times Toggles StickyKeys on and off.

That way when Word (on the client) helpfullly turns off the caps lock, it doesn't get toggled back on when I turn off the caps lock on the master. Ideally, it would just notice that Word turned off the caps lock on the client and turn it off on the master (and all other clients) too, but I think that's probably too complicated to implement. double clicking NT binaries fails (liz) add note to README or use separate binaries for services. client would also need a dialog to query options. server would probably need one too. use dialogs if there are no command line args. how to exit (liz) no good way to exit on windows win32 console disappears too quickly (liz) maybe show a message box if exiting to due an error better support for reloading configuration (liz) use SIGHUP on unix use an app message on win32 provide access through a control panel or taskbar icon non-functional on ctrl+alt+del screen in win2k (kurt) i suppose it must be when win2k is the client. mouse input wasn't working. keyboard probably didn't work either. --- automake stuff rebuild: * 'autoheader' - creates config.h.in * 'touch NEWS README AUTHORS ChangeLog' * 'touch stamp-h' * aclocal - adds aclocal.m4 to directory.
