Well, I'm a tinkerer, myself. It would sound plausible except for 
its having started on two separate machines at the same time. 
Another clue is that the symptoms aren't manifesting on the 
machine I'm typing this message, right now. This is a brand new 
FC5 installation on the same KVM as my FC4 box. On this machine, 
I haven't noticed any oversensitized mouse behavior, yet, though 
it's using the same mouse as my FC4 box... I tried turning down 
the double-click interval to a very slow setting on my home box 
this am, and things seemed to improve. If that doesn't bear out, 
I'll just try a new mouse...

Now, I was just thinking about this issue a moment ago, as I was 
preparing some lunch in my microwave at work. It has a single 
button for a 30 sec full power blast - I stuck my food in, pushed 
the button, and heard a double-beep - needless to say, when I 
looked at the timer display, it was counting down from 1 minute, 
NOT 30 sec - maybe my subject line is not so far-fetched ;-)
