---While we're on the subject of these events I'd like to point out that on WinXP SP2/ AS Perl 5.8.7, MRightUp is apparently not firing at all times.
If given a fair (say, 1 second) time span, it will indeed fire.If you are fast with your optical mouse, it may not fire at all, leaving you with a constantly stuck "down" state.
Although it RightClick will always fire. Hmm... Anyone else have this problem? Jason P
