The custom property tab hangs for about 5 seconds when it opens, or if you mistakenly leave it open, on a large variety of actions in SW. It has always had problems, but it seems to have gotten worse recently. I can't really understand it. Even if the thing has to go to the disk and pull up the entire template and all files every time for every action, it' impossible that this could take 5 seconds. It's hard to believe that it could take more than 100 ms or so. The property tab is a neat feature, but this makes it nearly unusable.
