Think you would find you had a very Disturbed Computer then how would it know which part of each window blind you wanted it to run and how would it stop the bits you did not want to run running.
It would know if you rename the blinds to the same name and tell you that you already had a file with this name so not to do it.
Open either skin in skinstudio and use the save as feature and rename the file to wahtever you want. It must be done in skinstudio or you will lose the skin.
Also, if any of the filenames end up being longer than 60 characters because of the full length of the name you will have to rename them to something shorter or they will not show in WB .
Thanks for the info it helped 100% and now I can have both Smooth x and Smooth X Vista Style installed
Now I have a new Question for these Skins
