When I installed Cursor FX, I soon noticed that I was having frequent random crashes of Windows Explorer. It would first crash (for no apparent reason than I clicked on a task, button or other control), then Dr. Watson would open up, crash also, then Dr. Watson would again attempt to run. After that, I am unable to click on any button task or other control. I am forced to do a three fingured salute to shut down the two crashed Dr. Watson's, after which my system would resume functioning in an apprently normal fashion again... at least until the next explorer crash. I rolled my system back to CursorXP, and all problems with Explorer crashing have gone away.
