Registered GameEx taking too long to exit

My GameEx is registered and all of the features are working. The wait on startup is gone, however when I shut down GameEx I go to a black screen for about 15-30 seconds until it shuts down completely. I've been told this is not normal behavior, and I expect GameEx to shut down instantly without the ridiculous wait. It's driving me mad. Any ideas?

I've attached the ini and log files in case you need them.
