Window position is off when resolution set to 300 percent

[Kyle Weber]

On my laptop with the resolution at 300 percent, software update shows just off center of the screen. If the window is maximized it will re-center, but then if you click install it will appear to freeze and will become unresponsive until the installation process has finished. Once it has finished installing, the window does not properly re-draw itself (see attachment--notice no borders around the dialog box).

See attachment for example.
