As soon as I began using OS X the screen shots I took were always saved as a preview document. I recently installed Adobe Acrobat 6 and since that time all my screen saves are saved as Acrobat documents, I would prefer to know where and how I can change the opening preferences of my screen shots from Acrobat to Preview - I do a lot of screenshots while I'm working on documents as well as browsing the net. I've been changing the opening preferences of each screen shot by going to "Get Info' and changing the 'Open with' preference. Its becoming rather tedious to do this change for all my screen shots, Isn't there are place where I can change the opening default for all my future screen shots ?
