If a control has focus, it shows the selected item in blue, and when it does not have focus, it shows the selected item in gray.
Sorry, I must be misunderstanding, because I'm seeing the opposite, I think.
If I click on any channel/query/notice window in the treebar, and it has focus, the highlight in the treebar is gray
If I click somewhere else on the treebar and lose focus (the chatbox cursor is no longer blinking), then the highlight is in blue (as before)
There is no way for me to chat in a channel or query and have it highlight blue in the treebar.
Just wanted to confirm if this is what you meant. Thanks again!
