(ver 1.2.1) No mouse pointer in the game!?

Subject: (ver 1.2.1) No mouse pointer in the game!? 2017-03-15, 09:08

Fresh install of HeroesII+PoL (but not the GoG version, my original CD version. ^^)
Ran the game, no mouse inside. With a good guess I can put the invisible cursor on the wanted button but mahh you got it (ver 1.2.1) No mouse pointer in the game!? 977280278

(ver 1.2.1) No mouse pointer in the game!? 977280278

and then I tried to put full screen... Game crashes. (ver 1.2.1) No mouse pointer in the game!? 3293758093

I try to re-open it, and it crashes? (I guess it's because it kept the Fullscreen mode...)

Uninstall/re-install.
Game crashes. (ver 1.2.1) No mouse pointer in the game!? 3293758093

Where is stored the windows size? (maybe if I turn of the full screen manually...)

With: Windows 10, laptop screen 16:9
