win32:
need to support window stations
login screen on NT is a separate window station
handle display changes
---
not handling international characters
---
don't allow leaving screen when any key is down
that includes shift keys and mouse buttons
caps lock, etc must not be down but can be on
not distinguishing between caps lock and shift lock
In Caps Lock mode, the alphabetic keys send their uppercase (shifted) char-
acter when pressed alone. 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.

problems with CLIPBOARD and KDE and NEdit
KDE mail reader (others?) and NEdit never reply to selection request
perhaps a general Motif problem?
currently sending all clipboards to all clients
some clients may not need all clipboards
add filtering mechanism
must find app that correctly sets the CLIPBOARD selection for testing
synergy must note changes to one or both selections
seems to be having trouble with noting CLIPBOARD after PRIMARY changes
investigate klipper
KDE's clipboard manager?
it crashed once when server did (see below)
---
got crash when opening netscape window after trying copy in KDE mail
BadWindow in ChangeWindowAttributes
also got it when trying to transfer big clipboard from secondary
or just after transferring and perhaps trying to set locally
---
sometimes not sending correct clipboard
some kind of race condition i think
can select text then switch and get empty clipboard
switching back to owner screen then out gets correct clipboard
---
screen resize should report new mouse position
client could change it to keep mouse on screen
server will need to know new position
may need to ignore mouse events sent after resize but before server
knows about the change.
not handling screen resizing yet
---
not handling screen saver at all yet
---
slow leaving primary screen on X
possibly due to getting primary clipboards
possibly something else
could try asynchronously getting primary clipboard
race condition on secondary wrt pasting
---
win32 hook DLL sometimes not unloaded when server is killed?
will get assertion on restart as if DLL was still loaded.
can tell because all DLL copies share data segment.
should prevent multiple copies from loading (or initializing)
replace asserts with (multithread locked) check of variables
return 0 if busy
server must handle failure
try to figure out why it's not unloading

test:
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 -> 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
shift, ctrl, alt not working

check accessibility shortcuts work on secondary

server asserts if two clients with same name try to connect
should simply refuse second client
also not reaping disconnects very fast
investigate slowness

replace all structs with classes
