Cannot drag and drop files

This problem emerged recently. When I attempt to drag and drop any
inconspicuous file from one folder to another absolutely nothing happens.
When I attempt to cut and paste instead, I get vista telling me the file is
in use - "The action can't be completed because the file is open in another
program." I can return several hours later and even sometimes after a reboot
and I still can't physically move the file. This is for any file type. Very
annoying.

Does anyone have a solution? Mine is not working either. I have found
that I cannot drag and drop a file into a folder within the same Windows
Explorer window. However, if I open another windows explorer window, I
can drag the file from one window to a folder in the next. Weird. And
extremely annoying.
