In the last few weeks I have noticed an annoying phenomenon.I load fs9, and then load any of the payware planes such as ther ATR-45 or the 737NG or the PSS airbuses.I also load Radar Contact as I prefer it to the fs9 atc.After the plane is ready to go, if I hit the alt key to access the top menu, the program crashes to the desktop. The weird thing is that when I use the alt key earlier, let's say to change fuel load, usually there is no ctd.Is this problem related to memory?Eytan OrnsteinP4 2.4 GHZ1GB DDRGeForce 5700 LE 128MB80GB hard drive

Just to add to the above, the following is the ms error report that I get after the ctd;:DOCUME~1eitanLOCALS~1TempWER5799.dir00Mini081707-01.dmpC:DOCUME~1eitanLOCALS~1TempWER5799.dir00sysdata.xmlEytan
