Wrong tab highlighted - minor bug

One of my listers has 8 tabs. When I select other than the opening tab, it is correctly highlighted. But when I select a folder under that tab, the highlight jumps to another tab further to the right.

No need to respond to this report, just put it on your 'that's interesting' list.

I'm using 10.1.0.0.4570.X64

Thanx for a fine product.

That isn't normal or something we've seen on our own machines. If you've got any suggestions on how to reproduce it we'll give them a try.
