I have a problem and it is getting worst with the update: in the UI the game is very slow. I do mean f***ing slow! After I clicked EXIT it takes 1 minute before the game actually closes - I can read the whole credits

Everything the UI is slow: when I click Tactical Engagement it takes ages to display the list of mission and when I select a mission it takes ages to display its details etc...
All is great once in the 3D game and all is terrible again once I'm back in the UI.
Is it a know problem?
I have a 2000+ 512MB with Win2K SP3 and a GeForce2 MX400 with nVidia 29.42
