I hope someone can help...I have been simming for years I have had the same set up since FSX came out...you can see it on the flight videos forum under 'my flight sim' (probably on the 2nd page by now) anyway, a strange thing has developed all aircraft now roll without any control inputs. I am flying straight and level and then all of a sudden it just starts to roll to the right then to the left. I thought it might be my ch yoke so I disabled it and flew via the keyboard and it did the same thing. I have re-calibrated the controls, I have adjusted the sensitivity and null zone, I can see the yoke moving appropriately in the VC but it just seems to have a mind of its own. This started, I hope coincidentally, after I purchased and installed FS Flying School, I have now uninstalled that program to see if that's the culprit (plus, I didn't like it that much) but it's still doing it. I have also checked all my flight failures to make sure nothing is armed. Any ideas?? Thanks.
