I'm getting weird COM exceptions. I can't seem to be able to click on (or execute Open command) on a drop down first time (then second time it opens and clicks on the right choice, but then it gives me COM exceptions... an example (I've also gotten System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL as well):

Hello Will,
Anthony
the Telerik team
Is this an HTML or Silverlight ComboBox? Is it a generic control or a RadControl?
We'd like to see the error first-hand to diagnose it. Please see here for what information to provide. If you can grant us access to your app but feel that information is sensitive, you can submit a support ticket which is confidential, unlike this forum.
If you can replicate the issue against a Telerik demo site (HTML or Silverlight), let's continue the discussion here. Please provide reproduction steps in that case.

Silverlight RadComboBox.
Good news, I was able to reproduce the issue with a demo project, I will be able to submit that with support ticket (corporate policy forbids us to submit any real code, only a demonstration, even for confidential support tickets).
Basically, have the SelectionChanged event wired to:
And then program Test Studio to:
Navigate to the Silverlight page.
Open action on drop down.
Select item 1.
Wait a few msec (for the page to refresh)
Open action on drop down.
Select item 2.
Wait a few msec
Open action on drop down
Select item 3
Or something similar to that.

That sounds good. Please attach the demo project (within a .zip file) to a new support ticket and reference this forum thread. I'll take ownership of the new ticket once it comes in.
