Hallo

I have been using dosbox for many years, for MsPacman and Qbert and it has worked very well, without any problem at all.

I updated to 74.3 (which may or may NOT be the reason for the problem, some changed display setting may also be) and now, when I press alt + enter, the black window goes large to full screen as always, but then vanishes completely, instead of as usual showing the game on full screen...
The second dosbox window, where I have as always used: strong + f12 to speed up, is still there and open....

The same thing happens with both games

I re-installed 74.... same problem

Thank you
