Problems extending GameViewportClient

[WilliamDocherty]

HI

I'm trying to create a custom GameViewportClient. I can get one to work fine in PIE/PC & the mobile previewer without any warnings/errors. However, when I run the app on a device it just crashes immediately after playing the UDK movie.

I've stripped my code down to it's simplest form to try and narrow down the problem - the following code just draws a semi-transparent square in the top left corner of the screen after everything has been rendered.

class Test_ViewportClient extends GameViewportClient;

event PostRender(Canvas Canvas)
{
	super.PostRender(Canvas);

	Canvas.SetDrawColor(0, 128, 0, 128);
	Canvas.SetPos(0,0);
	Canvas.DrawRect(Canvas.SizeX/2.0,Canvas.SizeY/2.0);		

}

DefaultProperties
{
}

& in DefaultEngine.ini

[Engine.Engine]
GameViewportClientClassName=Project1.Test_ViewportClient

Commenting out the ini file setting uses the normal GameViewportClient & my app runs fine.

Any ideas what's going on?

Cheers
William
