Yesterday I went into Excel to update a spreadsheet. After entering the information and hitting enter my sheet closed. I did this several times. I finally realized the file was a "read only", which is strange as I've been working on this sheet for 2 years, 2 or 3 times a week. I started saving the document under different names. I opened the file, and Tools and saw the "read only" box was blue. I removed it hit apply and clicked ok. No matter what I did it always went back to read only.
I created a new folder, began a new spreadsheet and the same things happend. Any suggestions?
