When I try to compile my futurebasic/program generator project, It says it is unable to access the resource file and that it may be open and in use by another application (and it is not). Booting up without extensions solves the problem. I suspect it is a conflict of some kind, possibly with Speed Doubler 8.1 or Surf Doubler 1.15. I haven't spent the time tracking this down. Running system 8.1 on umax 603e 240mhz machine. Anyone else experience this problem? By the way, speed doubler does seem to improve the performance of my application once it is "built" and all I am doing is running the application.
