textbox changes not saved

I have a problem making and saving changes to text boxes on my report and on sub-reports. If the text box is in the header and I change the text, save it, close the report and reopen it the changes have not been saved.

Any ideas?

Also, I've tried to make changes to a text box on a sub-report. Again, the same things happens. I've cycled through this about a dozen times and the changes don't get saved.

Do I need to delete the textbox and start over?
