blutok: I have a strange issue with a pointer in the game: sometimes it just doesn't do any action whenever i click (on the strategic map, city view and during battle) i have to click a lot sometimes to perform action. Any ideas? Changing settings with cursor rendering didn't helped. Windows 10 x64 game and windows Polish versions.

Plokite_Wolf: Does this happen with anything else on your computer? Might just be your mouse dying.

blutok: If this would happen to anything else i would have noticed :) Other HoMM games (1, 2, 3) works perfect, other games too. Surfing the internet cuases no problems, neither text editors. The problem occurs only during HoMM V play.

Thanks for trying anyway,

Plokite_Wolf: Try disabling full-screen optimization in the game EXE's properties.

blutok: Well it helped partially, action order is much better now, but sometimes my cursor changes to the windows one and can't perform selected action, however changing camera angle with keys helpes, not a big problem but annoying for sure ;-) thanks for help.

Plokite_Wolf: Only seen that happen with certain old 2D games... see if there's any other window "underneath" the game window that might be taking over priority for that part of the screen. Even some tray notifications like Windows messages and antivirus notifications.
