Has anyone ever had strands of guide hairs disappear when you use the “style hairs” tool?  I can use Poser for hours without trouble, then all the sudden I’ll notice one, two or more guide hairs simply disappear when I’m pulling them around with the styling tools.  If I keep going and not undo I’ll end up losing them all.  The population hair associated with these guides also disappears, even on render.  Sometimes restarting helps, but not always.  It is usually enough that I have to put the project away for a few days.  But then randomly, it will start again.  Any thoughts?
