Hey,
I have been making more edits to my innerspace folder a lot lately and I get tired of double saving. There used to be a post back in the day that would walk you through unlocking it. Anyway I did some research to find out if there is still a way to undo the "read only" mode without having to reinstall everything. Turns out there is... I use Windows 7 but I assume it works in general "use at your own risk" however, it worked fine for me. http://www.sevenforums.com/tutorials/1911-take-ownership-shortcut.html?ltr=T
