lol, what about copy ddraw.dll from 4.3 to 4.6 folder and have no problems at all?
Holy shit, you're a fucking genius. (OR I AM A MORON).
The main problem is that I can click on the second display when Im inside fullscreen WC2 4.6 and the game will minimize.
So this new ddraw doesn't block my cursor inside the game and let me click outside. The same problem was in 4.4, that's why I stayed on 4.3 (now I've remembered it).
With 4.3 it works very well, I can click only inside the game (1st display).
Anyway, It's not a big problem cuz not all WC2 players have 2 or more displays. And 4.3 was more than good for me.
I'll test some DDRAWs & combinations with 4.6 client.
