I'm having a problem with this build causing random crashes with FSOpen. I just get a message that Freespace 2 is no longer responding and it closes the program. I don't get an error log generated and don't get any error messages if I run the debug build. I went back to the 5063 build and the problem went away. I moved up to the 5068 build and it does not appear to have the problem. Since I didn't extensively test the 5069 build I don't know if it had the problem. I'll try the 5069 build and see if it has the problem and get back to you. I'm running an HP computer, quad core processor with 8 gig of ram, using windows Vista. I've got a Nvidia, geforce 9500 518 MB, video card. I'm running the Sync campaign and have everything set to high in the launcher with all the features enabled. I'm using the 3.6.10 media VPs.
