"Cannot remove folder new folder: the directory is not empty."

I am running windows xp (w/SP2) and have run into a problem at work and at home... I have trash in my recycle bin, but when I open (double click) on it, there is nothing there, and when I attempt to empty it (right click, empty) it tells me "Cannot remove folder New Folder: Directory is not empty".

I have searched google and these forums and can't seem to find any answers. Perhaps I missed it and someone can either answer or point me in the right direction?

Thanks!

Jeff
