Hey guys - nice work on Inspector Twain. I'm *very* happy to see it being used, especially by driver developers. Actually, I'm using Inspector Twain alongside my own Twister program as a test tool for a driver I'm writing... I don't know if there's a way we can collaborate - but I'm happy to help: Anything that improves the quality of TWAIN drivers helps everybody in the scanning business.
The annoyance of the subject is that every time I tell Vista (Business) to shut down, the process that prevents shutdown is the Inspector Twain updater. Looks like a 3rd party component, so presumably not your fault.
