Oo-er.. don't ya love it when that happens How are you at file associations?? Somewhere down the line, your sfp files have become associated with notepad (an easy thing to do if you try and open a file in notepad and don't untick the box asking if you always want to open the file in that program). Right click on the file (or one of the files) then select properties. You will see it associated with notepad. On the same line is a CHANGE button. Select the correct program type from the list and save. Your problem should go away
