@Mike Iacaruso On top of the other Mikes excellent suggestions please also try setting the 'Use Direct B2S in front end' to No in display settings. All of those settings will be easy to re-enable later if needed, so i'd suggest disabling them all and retesting.. if successful re-enable one at a time to see which is causing the issue, if unsuccessful then please re-attach new log and ini files after the test, and let us know if you did any software (or even hardware) changes when the problem first appeared.
@marcusvpcardoso Please create a new thread for your issue attaching your pinballx.ini and log.txt files and also more info on your issue (is the hang on exit only with Future Pinball, but other emulators exit ok?)
