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.

Couldn't reproduce on Windows 7 32-bit:

It's not dead. The website is temporary down, I'm trying to sort it out.

About the suggested feature, currently it's not planned.
