If it crashes too many times, a little pop-up window appears and Windows 7 (if you are running it) will step in and forcefully make adjustments to your system that
it thinks will help solve the issue. You can't stop Windows 7 from making the changes, and you can't undo them. Well, it says you can undo the changes, but it directs you to a developer web site with about 4,000 pages of info on how to do it ... so, when that happens, I always format, or do a system restore.
