I have noticed a bug with the latest version of GMS. When I try to print a contour map to a PDF file, the program starts processing segments of the map and then runs out of memory before it can get all panels. I have 16gig on this machine and when I check the task manager, GMS is using 15.8 gig. Before I start the print job, GMS is only using 182K, after printing 1 time, GMS is using 6 Gig, after making a second print, GMS crashes and is using 15.8 Gig. I am forced to restart GMS after every print job. It looks like the code is not releasing memory after each print job. The final PDF file when it works is only 230K.
