I've just become aware of an unusual "feature" of Word.
A user had a problem with an old version of an add-in. I could not find it under any of the startup or template paths specified under "Tools, Options, File Locations". All these templates are on the LAN.
I finally found the offending template on C:Program Files/Microsoft Office/Office/Startup - any templates in there are executed in preference to the templates in the user specified startup location.
Has anyone else seen this problem?
