What do you mean, it's not at the very bottom? Here it is, and it's certainly at the very bottom:

Just click on the taskbar? Both Ctrl+Alt+Tab and Win+Tab go away once you click on the taskbar.

Should be fixed in v5.10.0.1 beta, please try it.

See also this thread.

Please provide more details:

• What is your version of 7+ Taskbar Tweaker?
• What is your version of the explorer.exe file?
• Do other tweaker options work properly?
• Try to recreate a simple scenario as shown in the video here. In this simple scenario, does Notepad keep its order?
• If possible, upload a video that shows the problem.

Can you please specify your version of 7+ Taskbar Tweaker and your version of the explorer.exe file (in file properties)?

Perhaps you're using a vertical taskbar?

This option doesn't have effect on a vertical taskbar.

For Office apps in general, and Word and Excel in particular, I heard a number of complains about non-standard user experience behavior. See this comment, I believe that's the issue you're seeing. That's how Office was designed to work, and I don't plan to work around this with the tweaker.

I'm not sure what's about "Power Director", but I believe that's it's a similar situation in which a new window is created.

You might be able to mitigate this behavior by not disabling grouping or by using the option:
"When not grouping, place new items next to the existing ones"

I'm not sure about the "Cannot open library 5" message. If you know of a way to reproduce the problem, please tell me.

Regarding the combining issue, see the discussion here:

Closing as a duplicate.

Great, so I did understand it correctly when I closed the topic the first time.

Great, I'm glad that you solved the problem. The Windows spacing options are new to me as well, good to know about them.
