Desktop finger push-ups... WHEW! It tires me out just thinking about it!
; )
Download CCleaner and see what is starting up with your computer every time it boots up, it is also great at eliminating huge caches and repairing registry errors, and of course best of all, its free.
filehippo.com has a download for it
To be honest, the finger push-ups (clicks) aren't too bad, but I really hate the reverse crunches my index finger has to do with the wheel!
(I did find sommat neat - if I 'click' the wheel, the cursor turns into a bomb-sight and I can fly all around the page looking for targets!)
