While I was playing Heroes of Might and Magic IV (HOMM4) last night my cat wandered across the keyboard while I was in a combat screen. The result was that the terrain seemed to have a checkerboard pattern superimposed over it as in the image below:
I have no idea how to turn off that grid. I've tried everything short of a reinstall of the game.
Interestingly it looks like the combat grid that many players complain is missing from the game

. I'm sure my cat would help them out for a fee.
Any HOMM4 players know about this? I've Googled all the keyboard shortcuts, cheats, etc, and nothing seems to fit.
Edit This is so sad.

I've just opened the game again, entered a combat scene, checked the combat options and there it is: Show Combat Grid. I unchecked that and my problems were solved. I'll kill that damn cat. I wish I knew what the keyboard shortcut was that he used.
This has to rate as my most embarrassing post ever.
