Yeeeeah... digging through the code right now, and that's some very 
asinine code I'm looking at right there. Whoever made that change back 
in 2005 must have had their head screwed on backwards that day.

And I mean, VERY asinine.

I'll get that sorted out before the next beta, provided one of you folks 
submits an issue report on GitHub to remind me.
