I have a RadPane that is floating and when I drag it by the PaneHeader control the entire RadPane jumps to the point where I started dragging it from.
It works fine when dragging by the ToolWindow Header, but with my template I have completely removed the header from the ToolWindow template, so the only way to drag the RadPane is by the PaneHeader control.
Does this make sense? I can replicate this using the telerik demo app. I noticed this some months ago but never got around to logging the issue, so it's not a Q3 problem.
