Hi,

Let me start by saying I'm using the latest v9.1 data grid with AllowRecordFiltering set to True.  When I try to setup a custom filter, by choosing "custom" on the combobox, I get this nice "Custom Filter Selection" screen, however, when I click on the screen and try to move it or cancel the application crashes.  My WPF user control is being hosted on a win32 form using ElementHost.  Any help would be greatly appreciated.

Here is the stack trace.
