Visio Internal error 2132

[Dan_Solo]

We have an issue where certain users try to save a new Visio file directly
into SharePoint and they get an error message saying:

Visio internal error: #2132
Action 1004: Save

First try closing and reopening the file. Next try restarting Visio.

When the same user saves the file to their desktop and then tries adding it
to SharePoint it seems to work fine.

Any ideas?

Thanks
