I have an InfoPath 2007 addin that works correctly on about 95% of the installations and on the other 5% works about 90% of the time. On those machines where it fails, there is an 'invisible' instance of InfoPath still listed in the Task Manager processes list after everything has been closed.
If this invisible instance is present before the next launch of InfoPath, the addin appears to load properly, but the menu items never receive the click event. No errors, no failures, just no response.
I'm looking for direction here. Does anyone know what I might look for that could be causing InfoPath to not exit when closed? Could be in my add-in, could be in my form, could be in the installation? Any and all help would be appreciated.
