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.
