Others Playing QSP game, switched to pop out(Solved)

[MausMaus]

Was playing QSP game,I clicked the little box at top right,it switched to pop out modee. I then closed QSP but now the game wont reappear in QSP( i can hear the music playing tho) and I cant see any settings to switch it back.

Edit:Just incase happens to anyone else ,right click,then click main description then drag pop out into back into main window.
