Unreal Editor crashes on ResizeBrowser #87

Hi,

I updated the BLUI version in my project (UE 4.12.5). I am not really sure which commit I used before but it was version 3.1 already and before commit 73d4be5.

After updating blui the project compiled and started as expected but if I resize the viewport and call ResizeBrowser the Editor/Game crahes immediately.
I changed nothing in code.

Did you have any idea what could cause this crash?

The log shows this error:

`[2016.09.13-14.27.26:824][580]LogWindows:Error: === Critical error: ===
Fatal error: [UnrealEngine\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 717]
Rendering thread exception:
Fatal error!

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x00000058`

If necessary I setup a demo project with this problem.

Thanks and best regards,
Stephan
