whenever I try to use the pop up view window that I'm shoe to view external views from the virtual cockpit And vice versa, The one activated by the Default Key ( [ & ] ) my fsx freezes and then says fatal error has occurred? Has This happened anything else, and is there way to stop it?

Perhaps your computer is too weak to handle the additional processes with stability.

 

However, have you considered the following two tweaks?

HIGHMEMFIX=1 (a tweak that prevents graphics corruption)

UIAutomationCore.dll (a tweak that prevents memory issues that is probably most relevant to your issue)

 

I know I have been saying this a lot recently, but please see Word Not Allowed's Guide for detailed instructions regarding the use of these tweaks.

Cool thanks, I'll try it.
