In example Task Panel, if you click on toolbar button Search, then expand "When was it modified?" item and try to scoll the left view, the scrolling looks bad, lots of flickering, bad redrawing.

Any suggestions how to get rid of the extreme flikkering in the TaskPanels. I have added a dialog control when when resizing it flickers.

We don't let the docking panes update dynamically as the user resizes them. We wait until the user lets the mouse up to resize. Also my code resizes the task panel in a docking pane along with another window we have in the same docking pane and had lots of flickering if the user resizes the frame window. I found that I needed to add SWP_NOCOPYBITS to the flags sent to SetWindowPos. Flickering was greatly reduced when I modified the flag.

Now if I can just figure out how to keep all the dialogs added as items to a group from flickering whenever the user merely moves over the group headers ... CJ must be doing an invalidate of the entire group contents each time a mouse moves over a header. What a light show! Pink Floyd would be proud.
