Hi Alasdair, I also do not think it is OS related, since I have seen this 'sometimes' in Windows 7 64-bit, with AMD Radeon HD 7700 Series with (I hope) the latest Catalyst driver!
At the time I thought little of it since it seemed to go away a few seconds later... by itself... In the Catalyst Control Center it shows a Driver Package Version 8.961-120405a-137813C-ATI, Catalyst Version 12.1, dated 29-Feb-2012... Hmmm, contrary to last time I checked for updates, it does now report a later Catalyst version 12.8 available... will download and try that... Now shows driver 8.982-120727a-145524C-ATI in Catalyst 12.8, dated today... Just tried FG 2.8.9.4 with 777-200 and no problem, but as indicated it only happened 'sometimes' and was never able to isolate the specific scenario that caused it... maybe as you indicate it is a/c specific... Found any reason why adding the radar to the aircraft made it go away... Will keep testing with different aircraft... Regards, Geoff.
