I'm not sure what is going on but it seems that every time I spend some time toggling between camerviews, on about the fourth time, I get the hourglass and FSX crashes, restarts. I thought it had to do with the camerviews I configured on the Aircraft.CFG file. But I changed it several times, switched from 3D back to 2D in the settings. I thought it helped at first but then it crashed again. The following addons are installed:
Ultimate Terrain X (latest)
Ground Environment Xtreme v.105
Wilco's Airbus Vol. 1
Note: As of right now, this happens only to the Airbus addon. Maybe I'll reinstall that addon.
How old is your computer? Maybe that has something to do with it.
