Yeah, it's not really meant to fix things itself, but sometimes having extra code active and doing things can change behaviour. It may be somewhat of a clue to where to look for the devs, or it may not help at all!
I have the same problem with rfactor2 on Steam that won't close. Attached image link in imgur. If I point to these two squares and hit finish then it does close rFactor on Steam but I don't know what to do so I don't have to open the task manager every time to close it.
i resolved it previously( long ago ) by removing the logi profiler , however in the latest build the problem has persisted again all my steam friends are in rf2 - it leaves you on your friends lists as still in game clicking 'stop' in steam ends it , occasionally it stops on its own - but mostly not i have to think its a game breaker if your game wont close - it kind of a key part of making games - you want them to open sure - but users have to be able to close it too
1 - open any text editor 2 - paste this code: taskkill /F /IM rfactor2* /T 3 - save as (all types) name it something like killRF2.bat (.bat is mandatory) in somplace easy to find after an ALT-TAB 4 - thanks me later I use it for my dedicated server (yes also the dedicated server won't close) but I think it should work also for RF2 ps: Be aware, this batch close EVERYTING named "rfactor2somethingelse.anything". So if you have a dedicated server on your PC it will close also the server. If you have multiple servers it will close all the servers.
