Lately I cannot get through Longitude W7* 30.00' As soon as the nose of my plane hits this line my sim (P3D v4.5) freezes and will not restart. Sometime the sounds are still working but that's it. If I click on any of my screens (I am using 3) anything to do with the sim greys out and I have to shut it down . Sometimes it crashes to disk on it's own. As long as I stay away from that longitude all is well. I have tried crossing at different lattitudes, some as far away as 200 miles but I cannot get past it. I even tried setting my location on the map to be L W9* 30' and that doesn't work either. I am flying an A2A Piper Comanche 250 In that region I am using ORBX Global Base, Vector and Open LC Europe. This longitude runs through Portugal. I first noticed this one when I took off from LPCH to the north, after getting airbourne at the end of the runway I turn left to the west and go straight. It is not far to W7* 30.00'. I am curious if anyone else using ORBX is having a problem with crossing any longitudes. If anyone is using the same scenery as me and has some time to do an experiment please try this and let me know if you have any problems. I have also experienced this at other longitudes so maybe you have too. There was one that ran through Iceland, but I don't remember what it was.
