I’m a developer in charge of several custom Outlook forms that are part of
our product. The forms have been around for many years, and I didn’t
originally create them, but have to occasionally fix defects, add features,
etc.

Sometime within the last few changes that I’ve made, the forms have started
misbehaving in the following way: every time I run Outlook, the first time I
open each form, I will briefly see the “Installing form on your machine…”
pop-up message box. Formerly, this message would only appear once after
installing the product, but now, it appears every time I open the forms – but
only the FIRST time I open each form after running Outlook.

I used to think this was controlled by the version numbering in the .OFT
file, or it’s corresponding .CFG file (the forms are installed by calling
InstallForm with the .CFG file), but this time I’m baffled. Changing the
version numbers, or leaving them the same, seems to have no effect.

Has anyone seen this before? I’ve been looking at it for a few days now and
can find nothing. Does anyone have any information that might help me?
