This looked to be a really useful free utility for custmizing the Windows 7 taskbar so I downloaded it from the PC Adviser website. Given that the icons present on my taskbar are too large and too widely spaced this utility looked a must. That is it would be if I could get it to work. I have tried every manner of adjustment offered by the customizer window but nothing ever changes. Yes the taskbar is unlocked. After making desired adjustments have tried logging out and back in or even rebooting without success. Must be something I am missing but what? Help.
