I'm noticing that the GUI is overall pretty sluggish. The major components are trees, tabs & docking panes. When I select a node, there is a definite delay between the action and response. With something as simple as that it should be instantaneous, but I'm noticing a 2+ second delay which is just long enough for the user to think they need to click again. However, on a tree that does not use cells, it works fine. I tried running the app outside of visual studio and there is still some issue here. Also the sliding animation on the docked windows is very slow. I know if I show this to my users they will complain. Any idea as to what is causing my slow-down? I've run this on multiple machines inside and outside the debugging environment all to the same effect.
2 seconds is a long time, so you should report this as a bug.
