UltraEdit, UltraCompare, UEStudio forums

This happened to me a few times as well. The copy + paste randomly stops working, then starts working again once UE is restarted.

The slow rendering and cursor movement was one of the first things I noticed when I installed UEM. I'm running a 15" MBP (MacBookPro5,3). I'm hoping this is resolved soon since I already purchased my license.
