Hi,

I've curently have an application that crashes when a tooltip of a control is first displayed while it's parent dockpanel is floating, and then after it is docked and the tooltip is to display again, it crashes.

You can easily duplicate the crash by creating a form with a DockingManager and one DockPanel in the Designer.  Add a label to the dockpanel and add a ToolTipTextNeeded EventHandler.
 
1. Float the dockpanel by either dragging it or using the drop down menu.
2. Hover the mouse pointer over the label to see tooltip.
3. Re-dock the panel.
4. Hover the mouse point over the label and crash

I noticed similar behavior when using a auto-hidden dockpanel in the floating dockpanel.

I'm not sure if this occured before the ServicePack that attempts to fix the DockPanel Leaking issue or not.

Thanks,

John

I forgot to mention that currently also use another third party control that is hosted in a DockPanel, and instead of crashing when the tooltip is suposed to display after the Panel is re-docked, the tooltip doesn't work any more.    If like the simple example I described I first display a tooltip before floating the panel, all is good.
