Firefox 1.5.0.X cant copy/paste anything to clipboard – Scroll Wheel not Working

This is really funny.. My Firefox recently self-upgraded to 1.5.0.3. But this problem has been persistant since the first Firefox 1.5.0.1 release. It was really bugging me as I couldn't cut paste anything at all… Here's what seems to work…

1) Close all instances of firefox.

2) Goto c:\Program Files\Mozilla Firefox

2) Rename firefox.exe to afirefox.exe (or any other name for that matter).

3) Start the renamed executable
Now everything works fine I dont know why they cant fix this at Mozilla??
