On my web page I use a page menu bar (green) and a category menu bar (blue). I've noticed that the selected category is no longer highlighted (yellow) after clicking. No problem after selecting one of the pages.
This behaviour has changed from earlier versions. I found another web page where this is still working (see screen shots). This web site seems to use an older version of Atahualpa.
I guess that this is a bug of version 3.4.2. Can anybody please confirm this? Thanks!
