"Show this number of Recent Presentations" reverts to 5

[New Daddy]

Powerpoint 2013.

The "Show this number of Recent Presentations" option under the Advanced Options keeps reverting to 5. Really strange. Any idea?

Do you have this problem with other settings in the Options dialog?

Maybe. None I have noticed. This one I've noticed because it's so peculiar.

Could you try changing some other settings, and checking whether they revert? Thanks.

For some strange reason, it's the "Show this number of Recent Presentations" option that keeps reverting to 5.

Other options -- such as "Show this number of unpinned Recent Folders" -- stays at where it was previously.

Any clue?

[HansV]

I have no idea, sorry.

Does it revert back to 5 when PowerPoint is closed and reopened or when you reactivate the Options dialog?
Do you have any add-ins or startup macros that might re-adjust the value each time PowerPoint Opens or an add-in or macro is run?
