Some CTD Help Please

Hi All,Sorry to Drag this subject up again...Today I was trying a flight from EHAM (Default) to Faro.Evry time I was taxing out to the runway, I got a CTD. It seemded to be always triggered by switching views. I do have a lot of AI traffic from a mixture of UT and PAI and im using UT AFCADS for default scenery and the afcads that come with my payware/addon scenery. I was using Active sky.Now I just tried another flight from Torino in Italy to faro and so far so good im about 1.5 hours in to the flight and no CTD.Does anybody know whats going on? I am using the Fs2004 9.1 patch, but im getting a little scared as its bringing back memories of the pre patch CTD's. My FS has been very stable, till now.CheersJason
