Every time I use the EntityGroup function, the memory used by DraftSight jumps by about 20 megabytes. With each use, EntityGroup responds more and more slowly, and DraftSight uses up more and more RAM. Eventually, calling the EntityGroup command causes the program to hang, while the memory usage continues to increase until I kill DS in the task manager.

This is very annoying. Please fix.

I am using Windows Vista Home 64-bit on a Core2Duo P9600 with 4GB of RAM.
