Thanks for the info, Bela.

I think I figured out where the problem is.  Bochs is pretty slow, and
it takes a while for OSR5 to boot up.  So, while it's doing that, I
frequently switch to another X window and do other stuff.  It so
happens that I almost always use <alt><tab> to switch windows.  This
is caught by X, but is also passed on to OSR5.  That is, at least the
MAKE codes are passed on, but the BREAK codes are NOT.  Therefore,
OSR5 THINKS the <alt> key is pressed (since it got the make but not
the break), even though it is not (when the bochs X window regains
focus).  If I just press and release the <alt> key (after returning to
the bochs window), things start working normally again.  (That's also
why I had a hard time duplicating the problem on Friday:  I wasn't
switching between X windows.)

I'll have to think through how this could get fixed (or if it's
something that will have to be lived with).  It's kinda related to the
<alt><ctrl><Fn> switching between multiscreens in OSR5 and
pseudo-terminals (same as multiscreens) in Linux.  I would guess one
possible solution is to totally intercept all keyboard input before X
acts upon it (possible???) while bochs is the window in focus.  Then,
you'd have to use the mouse to change X window focus.  I'm not too
sure I like that...  Hummmm...


I've also been working on the font size issue.  Some changes to bochs
in this reguard has been committed to the CVS tree, which I'll have to
look at.  But this should be solved soon...

Thanks again,

Carl
