mugen 1.1 closing

[Rabbitxpp]

Whenever i put my mugen 1.1 in full screen it lowers on its own during game and keeps running than when i click my mugen tab it does it again after a few minute, can anyone help me with the issue here?

You're not accidentally hitting windows+D are you?

[Rabbitxpp]

no i dont believe so im using my arcade stick on it so im not hitting any keys

i think what you said was right about windows D because when my bro in law would play with me he used a p4 remote with joy to key and one of the buttons was mapped to D, after changing it seems to be fixed.
