When opening the About screen there are several issues.
First of them is the look of the border, the dropshadow appears to be off the location it's supposed to be when focused. When losing focus the border goes normal, yet the title bar remains off.
Also there is no close button appearing to easily close the window, you have to guess the area where it should be to close it...
An idea might also be to make it close when you click anywhere but on the about window.
And last but not least, you can open an infinite amount of About screens, simply keep clicking it.
Now I'm not sure this is caused by Alt.Binz itself or by the visual style I'm using, so I'll include a screenshot.
This issue will probably not have a high priority, though I report it anyway.
