Yes, You are right. Actually I found the problem earlier but forgot to update this issue. Actually, my autohotkey script running as administrator was opening the chrome and other apps as administrator. That was causing the trouble.
BTW, Thanks for a great software. It save my lot of time.
PS: I am not a Win App developer so I don't how it works. But, if there is a workaround that allow 7TT to work with app running as administrator, please implement it.
Now, I have disabled the Win key hotkeys using http://www.pctools.com/guides/registry/detail/549/ and now using AHK and 7+ Taskbar Tweaker as normal user. It solved my problem :)
