The World of Avlis

I'm not quite sure if this is where this sort of thing should go, but anyway...

I've been trying to link a trigger area transition to a door, so that going through the door takes you to the transition and vice-versa. Problem is, every time I try, it gives me a little screen (twice!) that tells me the program is unexpectedly being terminated. I've tried this a few times now, and it is beginning to bother me. Is this a bioware flaw (a known one?), an unknown bioware flaw, or simply my toolset being messed up?

If it is a bioflaw, I will go and post this over there. Just wanted to make sure it wasn't just me.

I've already come up with a work around; it doesn't complain if you manually set the tag without doing the whole 'set up area transitions' thing. How odd.
