The IDE cause a crash

hi guys;

I am just curious to why... When I am on the net using Explorer 8, or no program running, and double click the icon Arduino IDE 0022, OR the Processing 1.5.1... It crash my computer ! ... :stuck_out_tongue_closed_eyes: My system is Window XP.

Mind you, it is not all the time... only on occations... It just a nasty inconvinience. Good things I save my files all the time.

Anybody have any clue ?
