Hi, I have Windows 2000 Pro on a P4 2.4G with 768 megs of ram. My problem is, if I use my computer for a while and leave it on, I go to use the Add/Remove programs dialog box and nothing shows up. (Except for text at the top that says "Add/Remove Programs....." sometimes it works, sometimes it doesn't... if I restart my computer, everything is usually okay. Also when this happens, other things occur, such as I can't cut or paste and I can't move desktop or folder icons around...

any ideas?

Thank you!
