Designer Issues with Docking Manager

I'm using Windows Vista Ultimate and your 5.1 version of the windows tools. I've put a docking manager on a UserControl. Then attempting to dock a panel and your tab control.

I get all sorts of odd UserControl/Form resizing behavior in Designer when I save the form or try to adjust the width of a docked control. At times, it resizes the whole form to its max integer size or makes the docked control with so wide it can't see the other one and you can't resize it.

Is this a known issue on Windows Vista or a problem on XP as well?

Hi Robbe,

I am afraid that I am not able to reproduce the issue of incorrect resizing behaviour of the form or user control when the width of the docked control is adjusted with the attached sample.

Could you please modify the sample so that the issue could be seen clearly? Also please provide a video file showing the issue. This will help us to resolve the issue soon.
