Thank you for reporting this bug. We could not really reproduce that issue, but we added a check for possible null references, so at least the exception should not be thrown any more.

Did you add any custom items to the ToolBox or do you have any custom Windows Forms controls in your project?

Hi Alex, we are using a form as a menu for out tests. We start it by the following -

Dim testMenu As New Windows.Forms.Form
testMenu = New Menu
testMenu.ShowDialog

I can email you a screen capture if it helps(tried to attach but its blocked by out app proxy).

Thanks
Scott

Hi Scott!

We've fixed a bug, which can solve your problem too. This fix will be included in next version of Ranorex.
