I have a Dell Optiplex GX270 with Windows XP Home SP3. Everything works properly except for the right-click, and a few other things.So if I go into any hard drive, say click on a word document, and right-click it, it takes about 5-10 seconds with the loading mouse symbol for the computer to load the menu. Same happens with other file types, folders, etc. If I just right-click the white space in windows explorer, then the menu loads pretty much instantly. The long wait also happens when I cut or copy something, but doesn't when I paste. I have run the "Clipbrd" command and the clipboard is empty. Any ideas?
