When I open OpenSIMKit.jar, the window never shows any gui, aka it is completely transparent.

Eventually after I open the jar file, a window using the java icon (shown below) shows up on my taskbar but the window never actually appears.

I can tell it's in the foreground sometimes because I can't click on programs that are on a certain region of the screen where I assume that the window is, but it always shows up completely transparent.

Also, whenever I open it up for about 30 seconds, the window that is in the foreground starts glitching out.

My java version is Java 7 Update 51, I don't know if that version of java is causing the problem or not.
