Thanks to the two new contributors here.
I just installed and ran Defraggler the day before yesterday. In view of what you (kado897) posted, I'll bet that is what did it. Would you recommend NOT to use this program? Is there any way to keep it from removing RP's if I do use it?
Kaktussoft, I must admit to you that I wouldn't have any idea even how to do the things you refer to. Seems like I should know more for as long as I've had my computer, but I don't. And just when I think I've learned something I find out anew what a computer dummie I really am.
