Thanks to this forum I recently discovered the net highlighting capability in version 6.0.
I think that button works pretty much as desired when I select a net on the schematic. One thing that happens is that the footprints and tracks (which are not on that net) are dimmed. So far so good.
But if I exit that function (lets say I now hit the top right button in the schematic toolbar to select items) the footprints and tracks do not return to normal brightness. I can perform a fair amount of editing without the brightness restoring to normal. Actually it also seems that the previously-highlighted nets tend to remain highlighted even after I perform other actions. But it seems that if I click on a power port in the schematic, that restores the brightness to normal.
I had not previously been using the net highlighting function so I do not know if this is a new modus operandi. Is it my brain that is dim or is this a minor bug?
