Trainz

About one out of 4 times when I am Saving the program goes into a loop with the Trainz picture and the circulating grey and white boxes. I can't think of a way to troubleshoot this. Also, I can't find a way to get through the questions on the Help-Desk to report it. I do not believe it is causing any problems (Hopeful). I have to use the Task Manager to stop the program. Restart and it seems ok.
