It sounds like a COM add-in. If you customise your toolbars and drag the
button for COM add-ins from inside 'tools' section to your toolbar you
can click it to get a list of COM add-ins installed (for the current user).

If its not in there then it may have been installed for all users in
which case I don't think there is a UI way to turn it on and off. You
could delete its settings, or maybe change its load behaviour from the
HKLM registry hive.

Poorly written COM add-ins will give you the VBAIDE project explorer
update fail you are seeing.

So, it should be able to be removed from there.

Still wish I could just switch it on and off when desired, as opposed to
install/uninstall from Add/Remove

oh well.

by the way, I've noticed that other code modules are not properly closing
when files are closed, now that I've loaded Oracle BI, too. The file is
closed in the application window, but the code modules are still visible in
the VBE.

not good.
