Description

Hi,

all WinForms toolstrip's will move to the upper left corner when the form is minimized and restored.

The ToolBarBug.zip is a very simple WinForms solution to reproduce this beavior.

ToolBarBug.zip

a) Run the WinForm application with the two toolstips on the form. b) Remember the location of the two strips c) Mnimize the form to the task-bar of windows d) Re-show the form from task-bar

--> ToolStrip positions moved.

I think this is not the expected behavior of the toolstrips.

Kind regards Sylko
