I am using Access2007 with W7. It has worked well for a couple of years. All my files are saved as A2003.
All over sudden, when I go to to a form's design screen, I don't get that little square on upper left that lets me deal with form events, data, formats etc. If I right click on an empty space, select properties, I get the headings, but Data has no source name. This happens on several different files, so not just happening on Current DB. Have I inadvertently clicked something or is my program corrupt?
Very frustrating, any help much appreciated
