task bar buttons move after "swtiching user"

Why is it marked as a bug? Is it caused by 7+ Taskbar Tweaker, i.e. do you only see the issue when the tweaker is running?

Thanks for your attention to my comment.

I tried the following:

1. exit 7+ Taskbar Tweaker
2. Switch User
3. log back in

The
task bar buttons are in the same order, at least within the same
application.  in my case, I have about 20 Firefox windows open.  I use
the Firetitle extension to name each window and then I alphabetize the
taskbar buttons.  They stayed in that order when 7_ was NOT running, but
not when it was running (though they don't always reorder that much).

BTW,
I love your program.  I wouldn't consider using Windows 10 without it! 
This is a relatively minor issue, though I have recently started
"switching users" when I leave my PC (for privacy), so it is becoming a
bigger issue.

A couple of questions:

• How is the "switch user" step done? Where do you choose that option? Do I actually need more than one user to reproduce the issue? Does clicking "Win+L" and logging back in causes reordering, too?
• If you reset all of the tweaker's options to their default, does the reordering still happen?
• Is the issue specific to Firefox?
• Does the reordering happen only within button groups (e.g. shuffling the Firefox window), or between button groups too (e.g. shuffling the Firefox, Notepad, and Word)?

To switch user, I go to the Start menu and choose it from the various Shutdown options.  I have three users defined on my machine.  I don't know if "switch user" is available if there is only one user.

I tried Win+L once and it did NOT rearrange the buttons!

The issue is not specific to Firefox, at least in terms of buttons from different groups changing at least group position.  I noticed that buttons within Chrome stay in the same order.

Thanks for looking at this issue.

It seems like I need to create another user to see the "switch user" option.

Probably last question before I try to reproduce the issue: do you actually need to change a user to see the rearrangement? I mean, if you choose "switch user", and then choose the same user, does it still re-arrange?

I tried to reproduce the issue, but didn't succeed. A video of my attempt can be found here.

Also, you didn't answer my second bullet.

Again, thank you for your prompt attention to this matter.

When I went to your link, I just saw a screenshot, not a video, but that didn't matter.  I made my settings match yours (I presume the default) and the bug did NOT manifest itself.  Here is a list of the differences between the settings shown there and the ones I used (which DO manifest the bug):

y drag to reorder

n group by App ID
y don't group
y when not grouping..
y don't group pinned items

n use taskbar default settings
y don't combine grouped buttons

y cycle between taskbar buttons

y display seconds on the tray clock
y reserve empty space on taskbar

Here's a new video in another format, now with your settings:

Still, I could not reproduce the issue.
