HelloUnfortuantely I lost my FS2004 installation to a hardware failure and re-setup everything from scrtach (OS, FS...).On a trial flight I started getting a lot of building crashes during taxi or even while waiting on the runway for T/O clearance... (on various airports)I do have some add-ons, but haven't had this problem before.Any idea?Regards,NikP4 3.06 GHz, XP SP2, 2 GB RAM, Radeon X800Pro with Cat 4.8 drivers

Does it happen at specific airports? I encountered this problem with some add-on sceneries I designed. When I first started, I was not exporting with building crashes off in makemdl. You could always turn detect crashes off in the FS settings. That should at least let you fly without getting any crashes.Good luck.Adam

Thanks.Well, what puzzles me is, that I am not even moving the plane... i just stands there and after a while there comes building crash.Turned off the feature (and loose terrain crashes and A/C stress as well...). Will probably experiment with different airports to see if I find a pattern in that.
