This was intended.

If I'd use radio buttons, I'd have to add a third one witch says something like "Off (default)", which doesn't add much value, IMO.

Also, I might add another option here in the future, e.g. the start button. Then, you could choose both the notification area and the start button, but when you choose the whole taskbar, the other two gets unchecked. This won't work with radio buttons.

In general, the update uses the same parameter you've set when first installing the tweaker. You probably chose to put a link on the desktop, and then removed it manually.

This preference is saved in the following branch in the registry:

HKEY_CURRENT_USER\Software\7 Taskbar Tweaker

In the DWORD value:

MementoSection_DesktopLnk

Yours is probably set to 1, you can change it to 0 to avoid the shortcut creation.

It might be worth to check whether the shortcut was deleted manually, and avoid creating it in this case. I'll consider it for future versions.

Исправлено в v4.1.5. Спасибо!

You shouldn't hope for it.

There are other options, though, like decombine-on-hover and/or decombine-active.

It's not a bug, it's a feature ;)

I guess you (accidentally?) chose to never show labels for AIM's AppID.

Open Taskbar Inspector and right click on AIM's AppID.

Not a bug, moving to "Ideas".

Works fine for me on Windows 8 64-bit.

I can't do much based on this error message.

If you want to get this solved, contact me via email and I'll give you a test build, so we can see what is the reason of the failure.
