I have some issues with PMDG panels causing a freeze when pressing shift+. When i uninstall FS2crew the problem goes away. I have Sp1 and Acceleration. Have you had any other users reported similar issues.

Hello Mike,That's the first I've heard of that one I'm afraid.What key assignment on your computer is tied to Shift + ?Thanks,Bryan

It usually happens when I press shift+2 or 3 which is the 2d panel and overhead panel. i do believe that it is somehow linked to nvidia's drivers which give me no end of grief. I also noticed that radar contact causes me to loose the ability to use windowed mode. Something is causing havoc. I realize this is probably system specific and a nvidia problem. I also had this same problem with both programs on my old computer which i just turfed last week.
