...Yeah the only problem with Windowblinds is the conflicts it causes with some programs... Perssonally I woul drather not have any 3rd party app running & enjoy themes knowing that anytime I open a program I am opening a potential conflict.
I used windowblinds for quite a while before just switchung to the uxtheme.dll hack method. Now I have my themes & no problems to go along with them....Though I do have windowsFX that I load up on occasion....

..No it's not al that hard to reverse the uxtheme.dll method, but if you don't like the theme you load there is no need to change out the uxtheme.dll file, all it does is add the ability to use 3rd party themes.
