A few weeks ago something changed on my taskbar where the window bar that shows me that Mozilla Thunderbird is open, is not the same as the pinned icon. Notice in the attached screen shot how the thunderbird pinned icon is all the way on the left, but the open window bar/icon is all the way on the right - two separate things, not combined on the left as I would expect (the way other programs work and the way it used to work).
Does anyone know how to get them to "combine" and be placed where I have the 'pinned' icon?
Did you already try to delete the pinned shortcut, and create it again? I've seen this glitch before but I'm not sure what is causing it, but sometimes creating it again is all it takes.
Yes, first thing I tried was recreating the pin. Same problem. It also doesn't let me create a pin from the window bar if the application is open. I can only do it from the Zorin Start button and search for the app there, right click and pin.
I tried multiple different layouts and turning off the taskbar.. Same problem. I also tried moving the pinned position. That didn't help either.
I think it has to do with how Thunderbird gets installed and how it creates a desktop reachable icon. I am originally a windows guy so I have little knowledge about how Linux handles this scenario. But I recall during the instructions for installing Thunderbird it required a different approach. That being said, I have not gone as far as to uninstall Thuinderbird and try from scratch.
there are commands to create the desktop icon here. I tried redoing them. No change in behavior.
Correct. I remember there being a problem with one of the other versions having some type of major limitation (don't remember what the problem was or if it was the flat pack version).
I think mozilla is now using that almost firefox-looking icon for its current release. Just installed Q4OS on youngest's PC and that shown in your taskbar is the same in Q4OS when I installed Thunderbird.
And that was with the available Version's in Zorin? I wold make the Suggestion that You could try it with the Version from the Repo. You could install it with sudo apt install thunderbird or the Flatpak Version but when you already tried it ...
