Error in FSX Menu after flight with MD-11

Hello,I don't know if someone experienced the same strange behaviour as me. Everytime I did a flight with the MD-11 and ended it over the menu to go back to the FSX menu, the window with the plane in the freeflight menu in FS is completely black. During flight I had no errors. The planes are not showing anymore. When I try to restart the flight with the Fly now button brings me back to sim but with graphic errors. So I have to restart FSX and all is well again. This happens only with the MD-11. Has someone the same issues?I use Vista 64 with Nvidia 8800gt and latest drivers.thanksKai
