Just wanted to briefly report some unusual behavior:

I have only recently been experiencing some odd behavior, where whenever I wanted to close MRIcriGL (running on Windows 10) I get an error popping up telling me ".MRIcroGL12.ini cannot be created as it is being used by another program" with the options "OK" (keeping the window open) and "Abort" (which then closes the application). This persisted even when freshly installing MRIcroGL. 

(I had previosly mentioned running MRIcroGL in compatibility mode as a potential workaround but actually this did not resolve the problem).

Any suggestions are highly appreciated. 

Thanks for creating and continuously improving MRIcroGL!
