I have around a 1.5 million hand db. HEM2's performance over the last few months has been progressively degrading. It is now at the point where I am being forced to task manage restart as often as every 50 hands played. It is a serious problem, it causes mistakes, eats blinds, distracts and interrupts the continuity of play not to mention the serious overall time costs. The program is also lagging frequently. What can I do about this?
