Hi
I had problems with standard thinapp login script, becouse it was not working with AD security group as I expected. I created little login script, that register package only when it wasn't register earlier, and it can unregister application without access to package file (after you remove user from group that have access to package file).
I was looking for something like this before, so maybe somone will be happy to use it and eventually make it better
Best Regards
