Fences 6 - Tab group keeps coming undone
I have several tab groups on my desktop and the rest of them seem to be working fine.
However, I have one two tab group that every time I restart the computer it comes undone and they sit on top of each other slightly askew.
I can put them back together but the same thing happens again.
Anything I'm doing wrong? or any things I should look out for when combining fences into tab groups?
