I'm just observing a very odd behaviour when using UIStudio with Visual Studio 2005 beta 2. After following the hint I got a couple of day ago with the user control to get the docking working with the ToolStripContainer, I now add my dockmanager and a couple of tool windows to the user control. Up to that point everithing is fine, just if I add a TabStrip to the user control, I get this odd message when I exit Visual Studio:
The control MyManager.WorkArea has thrown an unhandled exception in the designer and has been disabled.
Cannot access a disposed object.
Oject name: 'TabStrip'.
In fact, stack trace is empty. MyManager is my project/namespace to which I added the WorkArea, which is the user control. The generated code however runs. Anybody seen something like this?
