AvalonDock and HexEditor don't play nicely with eachother

Some sort of weird WPF bug is happening when this Hex Editor and AvalonDock are used together. When you drag a Document-window with a Hex Editor to a different dock, an exception occurs during de GridResizing event.

System.NullReferenceException
  HResult=0x80004003
  Message=De objectverwijzing is niet op een exemplaar van een object ingesteld.
  Source=PresentationCore
  StackTrace:
....
   at System.Windows.Application.RunInternal(Window window)
   at System.Windows.Application.Run(Window window)
   at System.Windows.Application.Run()
   at WatchDogsLegion.App.Main()

Not sure if related, the Hex Editor also significantly slows down the application when it is resizing. Looking at the code, a lot is happening during a resize.

No problem, I’m very glad you have this thing at all! Saves me a lot of trouble having to make it myself 😃

Yea, I was looking for something like a “Pause” and “Unpause” when doing things like this. Perhaps its as easy as that solution?

PS. Suspend/Resume is the proper wording.

Get the last code and launch the AvalonDock sample projet (.Net 4.7)

it’s work fine for me… I hope will be ok for you
