win32 changes. replaced log dialog hack with a windows console 

window.  now attaching thread input queues as necessary. shifted
code around so toggling toggle keys is immediately reflected by
secondary screen's keyboard.  now setting extended key flag for
keys that need it.  fixed handling of shift + caps-lock.  added
handling of keys that should distinguish between left and right
but don't.  fixed get/set of active window on leave/enter of
primary screen.  replaced 1x1 primary window with a full screen
window to work around a problem with losing key events.  changed
calculation of mouse move deltas.
