Had a new experience today during the Pantellaria Scenario. My headset locked up, while the game apparently kept running in the background. Was very strange I was talking with my squaddies who were reporting me to be diving, while to my eyes I was locked on to the SL's six, although view in the headset was locked up, and other than that, and that it looked as if my plane was surrounded on all sides inside a black box. When I took the headset off the monitor looked as if it was normal in-game as I splatted into the water. After that I was in tower, as usual. I rebooted and relogged before I went back into the Scenario.
Strange, it's the only time I've seen this happen, and hope it doesn't happen again. The only thing I learned from it was if it happens again I should remove the rift, and see if I can finish out the sortie flying just using the monitor and hat-views. Any one else have any experience with this and any tips for fixes or avoiding it?
