Goodaltgamer: OK, I just tried out the SW pointed out by you:

IT WORKS!!!! (for the GOG Battle Isle Andosia War)

But maybe I wasn´t clear enough, which doesn´t NOW make sense at all:

I AM running ALL games in FULL mode!

So why is this tool, supposed to change a WINDOWed game into a FULLscreen game changing the behaviour of a fullscreen game?

Doesn´t really make sense.....

And by the way, as I stated the earth 2150 was NOT GOG, only a comparision, that other games (non-GOG) have the same problem ;)

About Windows version: I just tried a kind of really old game: Perry Rhodan made by fanpro, and it doesn´t have the title bar at all (Date 1996 and original ;) )

And that was the reason why I posted this in the general forum and not in BI, so other users might find this as well.

Merci beaucoup pour l'excellente aide

Still hoping to find the real reason behind.........

But don´t get me wrong, I would still like to know exactly why this happens ;)

And Hardrada: No I prefer open source :)

Goodaltgamer: That´s what I really don´t understand.......

That this title bar comes up in fullscreen mode. I could have understood in windowed mode and your work-around, but that it even affects fullscreen mode, is a bit beyond my imagination in the moment.

that´s why I hopped through different games and I can´t grasp get the similarities.

But me thinks: Windoofs (word play in German, doof means stupid) features you don´t need, but you get anyway.

Like that they removed the good old WORKING search!!!!!!!! (angry) and they call the new search a feature!!!

DyNaer: True, that's rather odd, but at least the side effect is positive ;)
