It maybe something i am doing, as i am using custom xml windows with python. The issues I have is changing windows the background image is remaining the same but when the window changes it flashes black then comes back.

First Window window id=13001

		<control type="image" id="1000">

			<height>1080</height>

			<width>1920</width>

		</control>

		<control type="image" id="1001">

			<height>1080</height>

			<width>1920</width>

			<animation effect="fade" delay="300" start="0" end="100" time="800">WindowOpen</animation>

		</control>

Second Window

		<control type="image" id="1000">

			<height>1080</height>

			<width>1920</width>

		</control>

		<control type="image" id="1001">

			<height>1080</height>

			<width>1920</width>

			<animation condition="!Window.Previous(13001)" effect="fade" delay="300" start="0" end="100" time="800">Conditional</animation>

		</control>

Is there something I am missing? I want there to be no transition between these to windows... If it can not be done please reply i can combine the 2 windows but at the moment the first window is at 395 lines of xml code and another 250 plus lines of code in python alone and i am just trying to slip them up one becuase they have different objectives and 2 is just to help orgainze the code.

Any help will be appercaited
