[BUG] weird typing glitch then crash

[mobius]

-I apologize I didn't remember to check what version I was using. Not even sure if it was a stable or the experimental.- ...making this difficult to trace. It has only happened once. It *may* have happened a long time ago, or something similar but if I'm remembering half correctly it was so long who knows. Right now it seems to be a rare thing. I definitely be more studious if it happens again.

I was using NL for a while, I had opened and closed several levels (I was checking my own levels and fixing things) then, all of a sudden I tried typing in the author field and my key strokes came up as weird symbols and I couldn't backspace.
Then an error message popped up, unfortunately I clicked away too fast and don't remember it but NL then crashed and I got too more errors;

access violation at address 00480C05 in module 'NL.exe'...

read of address 000003C8

Exception EAcessViolation ... at 000AB3B0
...
00000178

I have no idea what could've caused this and I've tried replicating it again by doing what I was doing but it hasn't worked.
All I was doing at the time was I opened a rock level, changed some one way arrows to another color then attempted to write my name in the author field.

The current editor will be incompatible with new formats, and too much work to adapt to them. If I do make an official editor (maybe not nessecary, since Nepster's editor exists) for new formats, it'll likely be written from scratch.
