[1.04b9] Mouseover menu graphical glitch

[demiare]

Well, picture should say everything, but here is how to reproduce:

1) Click through hex coordinates&terrain HUD to show menu.
2) Click on any other hex to hide it.
3) PROFIT! [:D] Coordinates&terrain HUD now broken until you do anything that force game UI to redraw itself (move screen/click on button and so on).

Again, terribly sorry for finding minor bugs. Guess I'm not so lucky / meticulous to find major ones. [:D]

No bug to small right?
I'll prioritize if necc, no worries.
But I couldn't repeat this, anybody else can?
