hello Perplexer ,
i've made a check with my configuration :
first i do not use the Favorite bar, but an extension : http://extension.maxthon.com/detail/index.php?view_id=3024.
As i place myself in the same config described , so do not open a new tab from .. : From the Favorite Bar as for my Extension , the link is opened on the current Tab but the focus stays in the Favorite Bar or Extension bar, the only case where it works is when the link is called from Maxnote itself ( because it opens a new tab ).
As i use "open a new tab from .." , the focus follows the opening of the new tab.
Following my experience in software dev, you could not consider that this way of working is buggy, as you open in front a window and acts in it, you fix the focus inside, you will certainly not accept that a windows that was in background before catch the focus, despite you change its content from an action from the first window.
Will say, thankfully !!!!
the fact of opening a new window is different, because in this case it's a different and deliberate function that you use, you open a new tab and pass the focus to it.
Is it more clear to you ?
