Yes, the special behavior of vendor branches is as you decribe. I never really dug into why or how CVS does implements that, but that's the behavior I remember always seeing.

Also, I've never used cvsgraph nor gone over how CVS treats branch revision numbers with a fine toothed come, but what you're describing there sounds normal to me, Tammy.

Ugh. I have to stop thinking about this... that is the solution!!!

:) It is rather ironic that in this case, had you been completely clueless and just ignored everything, you'd never have noticed the mistake in your cvs import command, you never would have suspected any problems at all, and everything, coincidentally, would have been fine!
