To answer your first question, "yes", not sure where I can get the information 'what windows thinks happened', except that it might be on the screen shot I added to my topic. The problem only started recently, I have been using version 4.934 since it came out without any problem. I tried version 4.931 with the same result. However, I installed version 4.930 and it workes fine, so I am sticking with it. There was a log file but I deleted it when I changed versions. I will stick with 4.930 for now, if the problem reoccurs I'll send you the log file.
I am using Prosim with FSX and a number of scenery addons.
