I am using the UltraDockWorkspace from NCEK v8.1. I have a basic layout with my shell form as an MDI parent and the UltraDockWorkspace and UltraMDITabbedWorkspace.
If I close the Shell form with an ultradockpane currently showing I get a NullReferenceException in UltraDockWorkspace.cs at line 134. Here is the stack trace. This does not happen if there are no floating or docked panes. Any ideas why this is happening? Thanks for your help!
