Hi there,

My problem is this very annoying unexpected message that began showing up four days ago: filename.xlsm is already open. Reopening will cause any changes you made to be discarded. Do you want to reopen filename.xlsm?

I'm running Windows 7 with MS Office 2010.

It pops up each time I open a particular Excel file via a desktop shortcut. I also have this particular file in a workspace shortcut and, thankfully, the other files in the workspace haven't been affected.

I've spent a considerable amount of time searching the net for a solution, I've not come across a solution for this exact issue. I did find a previous post (http://www.excelforum.com/excel-gene...discarded.html), but there was no solution posted (that I could find).

Any help will be very much appreciated.

Thanks!
