FSX-MS FSX Freezing

[bigsky10 3]

Hi everyone.  I got a small problem I hope someone might give me some ideas on.  I am running REX Essentials plus overdrive with FSX.  I have GTN750 installed. It doesn’t matter sometimes how long you are flying but tonight about 1.5 hours into the flight with the Carenado PC12,  FSX minimized into the taskbar and nothing will happen. This usually happens with multi-leg flights. If I shut down FSX and start over again after every landing it doesn’t  happen.  I can go to the task bar and maximize or minimize REX but when I try to maximize FSX and fly again I get a message saying FSX is already running.  The only option I have is to close all the programs.   

I am running an Intel  Core i5 CPU , 750 @ 2.67GHz 2.66GHz. Windows 7 home Premium 64-bit, SP1  operating system, 10 GB RAM.  Video card is NVIDA GeForce 220 with 1GB RAM.

I have made the standard tweaks to the settings and to FSX Config file.
