So it come to my attention that in Gog version of Panzer General 2 if I use ALT+TAB game normally work no matter how many times I use ALT+TAB. But if I launch PG 2 cd version or let say People General or Pacific General and use ALT+TAB then it is 100% CTD. Are there any chance to make those General games work with ALT+TAB combination?

Have you tried it with (older?) versions of DxWnd?

Nope. Thx for info.
