Crash in DeactivateTaskbarFix

See original GitHub issue

I have daily users getting crash in the following method (I am not using directly ControlzEx but Mahapps)

  • ControlzEx :
  • Mahapps :
  • VS 2017
  • Framework 4.6.2
  • Windows 6.3.17134.0 (for this one but happens on multiple version)

Anything I can do to at least trap it and avoid a crash?

System.ComponentModel.Win32Exception: El identificador de la ventana no es válido

   en ControlzEx.Behaviors.WindowChromeBehavior.HandleMaximize()

I get this as well but it seems like the WindowChromeBehavior class has been refactored because the DeactivateTaskbarFix is no longer there. According to @punker76 there will be a new release of ControlzEx as soon as the next version of MahApps is ready.

You might want to make a branch and try to upgrade MahApps to latest alpha 2.0.0 and see if that works. You will get the new ControlzEx release then. Not sure how stable MahApps 2.0.0 alpha is. Maybe ask @punker76 if 2.0.0 is near release or unstable.
