Architecture: i386
Machine: i386
>Description:
	The code misinterprets "key" press events as either a motion event,
    a button up/down event or both.
>How-To-Repeat:
	press any "key" on a MouseRemote ( or compatible );
	- watch the mouse and or cursor do strange things and/or lock-up
>Fix:
	Diff of code to simply discard key presses ( w/ residual debugging
code to print them if desired -- may be GC'd ).
