Just did a mistake while reinstalling msys in windows, installed gcc instead of the w64-x86_64 version, very easy to do and you are in a hell of trouble if you do it.
Anyway problem fixed, back to sanity, but I had to delete the whole msys directory and restart from scratch to fix it... what a mess... !
I'll let a little time pass to cool down, I'll see what I'll do about this, but yeah removing all this and switch raine to fullscreen all the time is quite tempting I must say !
It's ffman1985 who was confused, and he is not really a basic user, and I suspect a lot of users were too. I don't see any problem with the current way things are done anyway.
