Paul, thanks for filling me in on SharePoint. It sounds like
the problem might be related to the innate lack of compatibility
between the "old" program (Captivate 2) and the "new" OS (Vista).
In your position, I think I'd be tempted to load another copy
of Captivate on a WinXP system, at least to create the recording,
then perhaps move the *.CP file to your Vista system for editing.
That is, until you are able to upgrade your Captivate to
Version 3, which as Rick said, has been tested for compatibility
with the Vista OS. Hope this helps ...
