I noticed some differences between the files you provided and likely this is a result of you trying to diagnose your problems with the crashes. In the first you were running BlueEx 800 x 600 theme, then Default-Default in the second. While I see no problem there, I did notice that in the first your "Display is running at: 1024x768 32bit color, 75hz" while in the second "Display is running at: 1024x768 32bit color, 85hz". Are you tinkering with your video adapter settings as well? Keep in mind that it is easier for us to help diagnose the issue if you keep the settings consistant with where you encountered the problem and make changes only as suggested to themes, screen res, etc. Much easier to shoot a stationary target!
