Bug (minor): XFree86 loses state of caps lock


I'm running XFree86 on cygwin under Windows 2000 (output of cygcheck is
below) and have come accross the following minor bug: it is possible to make
XFree86 think that the caps lock state is the opposite of what the rest of
Windows and the caps locks keyboard LED think.

To reproduce this:
(1) Run XWin using the standard startxwin.sh
(2) Click in the root window to get twm to place the xterm window somewhere,
and place the mouse cursor in the xterm window, so the xterm has keyboard
focus (actually, as far as I can tell, it's possible to reproduce this bug
in an xterm at any time, not just immediately after XWin startup)
(3) Press caps lock, but don't release it
(4) While continuing to hold down caps lock, move the mouse cursor over one
of the program icons in the windows task bar, e.g. Internet Explorer
(5) Release caps lock with the mouse cursor over the program icon
(6) Set the focus once more on the xterm & type some letters: xterm and
other XFree86-hosted applications behave as if caps lock is off, but the
caps lock LED light on the keyboard is on, and all Windows applications
behave as if caps lock is on.  If you press caps lock again, the reverse is
true.  Thus XFree86 has the opposite state of the caps lock key.

Although the steps to reproduce the problem seem obscure, I somehow manage
to do it surprisingly often -- I'm not sure why I hit caps lock at all, but
I apparently do.  But, this is clearly a minor bug and some of the
workarounds are obvious.

Workarounds:
- (obvious) quit & re-start XFree86
- (obvious) Toggle caps lock when switching between a Windows and an
XFree86-hosted application, or use the shift key to type letters in the
correct case
- Perform the above steps that reproduce the problem, which will put XFree86
back in sync with Windows

The rest of this message is the output of cygcheck -s -v -r:
