"Irritatingly unpredictable" is exactly what I was seeing.  It would work 
fine for a while and then switch to ptoducing a random number of button 
events for a given click.  I could even see this if I was attempting 
to "drag and drop" something since the hand icon would litterally open and 
close even though the left button was being continuously held down.  I 
would have to wait until it setlled into a "button down" state before 
dragging whatever it was.  Even then it would sometimes randomly produce 
a "button up" event and the drag would end up someplace other than what I 
wanted.

New mouse installed last night.  Works great.  A click is a click is a 
click....  It's some OEM brand I had never heard of but it was the only 
USB wired mouse that my local Best Buy had.  I usually buy hardware at our 
local Micro Center but that is about 15 miles away and I couldn't see 
going that far just to save a couple of bucks and get their never heard of 
before brnad OEM mouse.

Cheers,
Dave
