On Access 2007 I needed to change some of the fields. First I went to the table to change them. I was able to save changes. Then I had to go into the forms to delete those fields and then put them back in (so that now it would be the updated version of those fields). I hit "save" on the form but nothing seemed to happen. When I tried to close the form it prompted me with "Do you want to save changes to the design of form whatever". I hit "yes," nothing happened. This went on over and over. The only way for me to close the form is to choose to not save the design changes.
I opened a different form and tried deleting some other field. Same thing. I don't think its simply a matter of me having a corrupt form because I have this problem with all the forms. But it DID let me save changes to the table.
