Hrm. Must be a very rare bug in popup2. But since it doesn't seem reproducable (no such problems over here for example) it'll be a bit hard to track down. Do you have MSVC installed so that you could step through it yourself? If not... what happens if you create a new directory, copy over all the shortcuts and then point popup2 at that new dir? Does it still double everything? If so, does it still do it if you delete all but one shortcut?
