I have run into a problem that is becoming a considerable hinderance in
using, and enjoying, some of my software and my MAC SE (dual-floppy).

Last thursday I got Wizardry by Sir Tech.  I noticed when moving through the
maze it would often respond with TWO clicks when I had only clicked on the 
mouse ONCE!  This caused me to do a lot of back-tracking and generally diluted
my enjoyment of the game.  I switched to using the keyboard for movement and had
NO double-click problems as I had with the mouse.  I was getting a double-click
~20-25% of the time.  I thought that it might be because of my installing the
newest System files from the SE into the Wizardry backup disk, but upon
putting the original older System Files back into my back-up I still had the
same problem, so I don't believe it's with the System files.  I did call
Sir Tech yesterday and asked them if it could be a bug in the software and
they said they'd look into it.

Then, last night, I was using Professional Composer and trying to create a
new score, and things started going crazy with erroneous double-clicking!
Two notes were appearing when I had only cliked for one (forcing me to waste
a LOT of time deleting notes).  Whole measures would sometimes become
highlighted when I had only meant to click on a single note!  This was the
first time I'd tried using Composer in a week, and it is the first time
since I got Wizardry and began having this problem that it's shown up in
Composer.  I have not dropped, nor otherwise mishandled the mouse, but I'm
really concerned with what's wrong.  I don't like spending thousands of
dollars on computer hardware and software and then not have it function
properly when I've had it LESS than three weeks!  

Could someone out there please offer some suggestions on fixing this
problem!

Thanks.
