So... I hope no one minds me commenting here, just thought I'd give it a shot.
I noticed the print screen issue while trying to take some screenshots of my progress on a different issue. I took a few minutes to just dig around in the debugger, and it seems as if e.key.code is unknown at -1, and thus causes an array bounds error.

...

So, I played around with it a little more, and used some debug info to find this...

The key takeaway here is at the bottom, where e.key.code is unknown (-1).
Just to test, I started printing e.key.code. I did a few test prints, and then tried prtScm, and got...

The value of -1 then, of course, will cause an array out of bounds error.

I'm sure I'm just stating the obvious, but I thought it's better to have it set in stone than not at all. We might be able to deal with this by ignoring any unknown codes.

Thank you for all your time! Have a wonderful day!
