When using any theme it breaks my taskbar, start menu and start button. I know how to block start button/menu changes but not taskbar.
How can I make it so themes can't change my taskbar?
change it first before it changes yours 
prepare a black square image 40x40 px, save it twice, 1 as png, 1 as bmp.
open skin in sks, go to startmenu & taskbar > taskbar > horizontal taskbar > background > click tab image > look at the skin image for taskbar, if it's a bmp, import your bmp to replace it, if it's a tga, import your png to replace it, then click apply.
