HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

I have a question. I like to play in 800*600 resolution in windowed mode, but often when I click on the map with the mouse, I accidentally click on the game and shift it by a millimeter. This causes the graphics to blur.

The hero Rissa is in the Adventure panel, but she is not on the map. And when I hover the cursor over Rissa, the game crashes.
