Beginning of mission text not disappearing in Kola Instant Action

[Youtch]

Hello,

 

I have encountered a problem that happened for me only when flying Instant Action missions in Kola.

It happened with all the planes but just for Kola map.

The text with instructions provided at the very beginning of the mission when you are already in flights remains displayed on screen for the whole mission, regarless if I hit spacebar or not.

Any idea why and how I could solve this?

This is quite annoying to do all the mission with a text box on the screen.

 

Many thanks in advance,

y.
