Hi,
I found a bug during testing.
Currently I'm using RadControls for WinForms Q2 2011
To replicate the problem
-Run the Telerik Demo
-Grid View > Hierarchy > Tabbed Views
-Page View Mode = Explorer Bar
-Expand/Collapse twice the child data
-a hanging messagebox appears "RadControls for Winforms Q2 2011 SP1 Demo Application"
it also happened to my project.
EDIT: I attached a screenshot
