Has anyone come across a bug in Powerplay version 6.61 onwards? After upgrading from 6.5 to 6.61+ my users PC's started to crash quite frequently. After much testing I noticed that the memory usage was rising very quickly until the PC crashed. Doing the same exercise with 6.5 worked perfect and so that is the version still been used by certain departments. I believe the problem is related to the undo feature (ie turning undo levels to 0 works but users need the undo function). Any comments on this would be greatly appreciated.
