Hi Petr, looks like a bug in Windows. On a program that uses an old-fashioned type Windows menu bar at the top of the screen, tapping Alt activates the menu and enters a modal loop inside Windows to process stuff related to the menu like using arrow keys to move up and down, etc..

Since MoI does not have one of those menus, you would think that Windows would not try to do any menu processing for it.... however, the problem is that it still enters that modal menu loop even though there is no menu to do anything with.

I'll take a look, it should be pretty easy to fix up. Thanks for reporting it!
