Excel 2007 & Windows Explorer
 

I have a user who is running Office 2007, and when she has an excel doc open,
then goes to Windows Explorer to look for other file(s), locates, and double
clicks on the new doc, the new doc opens, but the windows explorer window
remains on top. I have already gone in and ensured that the option in excel
to ignore is unchecked (Office Button, Excel Options, Advanced, Ignore other
applications that use Dynamic Data Exchange (DDE)). This didn't do anything
to help.

Any other suggestions so that the new excel document opens on the screen so
that the user can see it rather than the Windows Explorer window?
