From Windows Explorer (or any other way), if I select a file, right-click on "Copy", go to another location (folder, drive, etc...), and right-click on "Paste", all I get is an error message sound (PLIM!). The file does not get pasted, and an error message is not displayed. I downloaded the microsoft patches KB823980 and KB833330, but they did not resolve the problem. I also ran spybot and adaware on the computer to no avail. I am not sure if this is related to this issue, but this problem started happening after I installed in the computer a Visual Basic application that I wrote and which needs a lot of dlls to be able to talk to Crystal Reports and SQL Server 2000. I uninstalled the application, but the copy/paste problem is still happening. I am starting to feel I little hopeless and would appreciate any help you guys could give me.
