hidden macro affects how other files open
 

I have a macro sitting in the folder

C:\Documents and Settings\user-name\Application Data\Microsoft\Excel
\XLSTART

The worksheet in the excel file with macro itself is "hidden". When I
open other excel files they would not show data upon opening. I need
to do Windows, Unhide, Cancel to get them to show data. Instead of
Cancel in the Unhide popup window I can select the macro (which is the
only name in it which makes sense as the real file with data is not
hidden) and unhide it - the file with data will also show... The
problem exist only on one computer - same macro on other machines does
not prevent other files to be visible upon opening. If I delete the
file with macro, everything opens up normally. So, the fact that a
file with hidden worksheet exists in the XLSTART folder somehow
affects what Excel shows. I assume an Excel setting on that machine
should be tweaked but do not see which one.

Any ideas?

Thanks a lot
