[hpsdr] Crash in mx PowerSDR_mRX_v3.0.0.0

[chris at chrismitchellhome.net]

Environment: Windows 8, 64-bit



I'm getting a NullReferenceException in PowerSDR.Display.Target.set() on line 419.

Quick inspection in the debugger suggests that console is null.  Dispay.console is set later in Console.Console(...) than where I've progressed.

Looks like the ResumeLayouts are causing resizes before we're ready and the resizes are calling into console/display before inited.



Placing a null check in Target.set() seemed to have fixed the crash, implying there were no other problems.

I have two machines: one does this and the other doesn't.  I haven't attempted to debug both yet, but wanted to pass it on nonetheless.
