By the way, I noticed there's a memory leak when clicking the Refresh button in the Report window. Every time it's clicked, something isn't being destroyed properly, resulting in increasing memory usage by S+. Will find out where the problem is and correct in 1.5.8.
For the interim, don't click the Refresh button over and over =)
Actually, the image lists for the tree in Actions and Report have hard to find memory leaks...
Each time you see either the Report window or the Action window, S+ is consuming a little more memory. I'd recommend running 1.5.2 until these leaks are resolved, but will leave the releases since then here for historical purposes and for those who understand and accept the issue.
