If doing a long flight, P3D will close with an error if the window is either minimized or if I have another window open over it like a browser or other application. There will a popup showing the following:

The error in the event log is as follows:
Faulting application name: Prepar3D.exe, version: 2.0.9448.0, time stamp: 0x528edbf4
Faulting module name: MSVCR100.dll, version: 10.0.40219.325, time stamp: 0x4df2be1e
Exception code: 0x40000015
Fault offset: 0x0008d6fd
Faulting process id: 0x20a0
Faulting application start time: 0x01cef1e7166ab416
Faulting application path: C:\Program Files (x86)\Lockheed Martin\Prepar3D v2\Prepar3D.exe
Faulting module path: C:\Windows\system32\MSVCR100.dll
Report Id: e4b144b0-5de6-11e3-b37a-3c970e67be26
This makes it challenging to do something else like check email while on a two or three hour flight....
Any ideas?
