Hi Bert, Yes, it's a dual core machine. With 4 GB of RAM. I guess it just seems strange that it would limit itself at 50% when other processess use as much as they need when they need it. If it needs more memory, and is generating memory allocations errors as a result, doesn't it seems like it should be able to use it if it's there and available? I guess I'm just a little stumped.
