I decided to test on the little frog (Zygotes?), which have smaller cr2 file.

Put one hair group on him, saved whole figure to char lib.
Added the lines in the cr2 file.
Loaded the froggie.
Loaded without error. And without hair! Not even the guide hairs.
On the other hand I got one more frog in the deal. ;o)

It is getting late here and my personel that runs the brain department is leaving for home. Can't trust them workers now a days... Will look at it tomorrow.

Goodnight everybody. And thank you!
