Null Pointer Exception running 3.7.4 on Windows 7

I just downloaded & installed iReport 3.7.4 on my Windows 7 Pro laptop and while the program is loading up I get the following error message...

I loaded it on another of our developer laptops running Windows 7 Pro and it did the same thing, but I loaded it on one running Windows XP Pro and it seems to work fine. The second and third laptops were identical except OS so it must either be a video card driver issue or an issue with the Windows 7 visual options, I'm thinking.

Alas, this was a java issue with the theme on my computer... For more information you can go to http://forums.sun.com/thread.jspa?threadID=667836 I set my theme to Windows Classic and everything worked fine. Incidentally, I am running Java 1.5.0_06

Changing my Windows 7 theme took care of the Null pointer Exception error for me as well.  How strange. 

THANK YOU!!
