GuiShowImgCtrl's sometimes does not update when in an external window.

Try the attached script (I tried to put it in this post, but got that stupid security error)

When you press change image while the window is internal, it will update with no problems.
When you pop the window out, then press change image, it will usually change once, then stay at that image until the window is resized.

Note: The image is actually changed. If you echo the GuiShowImgCtrl image after changing, it is changed. The image itself is just not updated.
