Are you using the VFR Addons' Autogen? If so that seems to affect my afflicted machine, in the Gloucester area.

Now that is very interesting!
One of the Cix VFR Club's operating bases is Gloucestershire, and therefore it is around the south/south west area that I end up doing a lot of my flying. It is in that area that I get the "jerks", although I haven't done proper tests to see where else I get them. I wonder if it something to do with Gary Summons' EGBJ secenery which does seem to load up the system a lot. However, I don't think I get it around Biggin Hill, which is the Club's other base, and also has Gary's scenery. I'll have to recheck next time I get a minute (next week probably!)
