User security inverts in Citrix session

Yep, that's right.  One user in my domain logs into Citrix farm and works along until she is no longer able to access her drive on the share.  Looking closer freaks me out, because she can access all other folders!  Not her own, but every other folder.  Closing Citrix session and going back in fixes it, but it won't last.  What could she be doing to make this happen?  10 plus years as sys admin, I have never seen anything like this.  Am I blessed?

I have nuked the roaming profile a few times, replaced her PC, had her work fron a Wyse terminal, it still happens.  She is now running a new default profile on a different PC, and it has happened twice today.

Gurus, what y'all got?
