Are you located in one of the following locations?
China, Japan, Hong Kong, Korea, Thailand, Taiwan.
The hosting had issues with those before.

Currently, Windows 8.1 Update 1 (and the equivalent server version) are not supported.
More information: 7+ Taskbar Tweaker and Windows 8.1 Update 1

Fixed in v4.4.6.2 beta.

I can't reproduce the issue.
Please provide more details, such as:

• A crash report.
• A screenshot.
• Your OS version.
• Your configuration of the tweaker.
• Your configuration of the taskbar (Taskbar Properties).

The padding only affects the icons which are located on the taskbar. This is by design.
I thought about changing it for the popup too, but came to the conclusion that the feature is not necessary there, as the icons do not take valuable space (like they do on the taskbar).

Well, I guess you don't need that feature then.

Feel free to create a new topic about it.
