I've noticed that Poser 8 doesn't much like underscores either. Perhaps it's both dashes and underscores that cause problems? 

I'm not sure how consistent it is though. The very first day I tried Poser 8, I had this problem, but after a reboot it went away. Doesn't make any sense of course, but there you are.. glitches never do :)

I hope it's solved. I don't like the fact that Poser internally just decides to skip letters in a filename...

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
