Something has started happening within the last couple of weeks that is really odd.

I have an Excel 2013 file that contains several macros. It has been working for since early 2013 I would guess and has had no real problems. But now if I try running the macro from the "View Macros" menu that I've placed on the "Quick Access Toolbar" Excel freezes up. However, if I open the VBA editor and run the macro from it, the macro runs fine.

The macros have not changed in the slightest lately. This is at work, so the only thing that could have changed lately is the installation of patches sent to us from Microsoft and delivered to the end users by our IT department. But this is only happening with this one file.

Has anyone out there heard of this happening?
Thanks.
