Got an annoying problem at my work computer: When I try to drag and drop a file onto a menu/button to copy the file to a folder listed there, the menu pops up and then instantly disapears again, making it impossible to drop the file anywhere. I suppose the problem lies with Windows, but I haven't found a solution for it. It's a rather fresh install of Win2k/Sp2, and it worked fine before I reinstalled the computer.
Any ideas? The menus works fine in every other way, except for drag'n drop.
