Please offer some advice.

There's an issue: when I launch the game, a bar appears at the top of the screen, similar to the menu in Equilibris. It's not a major problem in itself, but during battles, it obscures part of the battlefield, making it difficult to see where the creatures are located.
One workaround is to switch to an 800x600 resolution and then back to the original, but this needs to be done frequently because the bar reappears after each tab switch.
This problem started relatively recently; in the 10 years I've been playing Heroes, it's only been happening for the past year or so.
