On Close form not saving

[Razor1]

I am changing the row source on a Multi Select List Box and then saving the form and then reopening the form. When I close the reopened form a dialog box opens and asks if I want to save the changes. There has been no changes to the form since I opened it.

Here is the code I am using:
DoCmd.OpenForm "Form1", acDesign
Forms!Form1!Choice.RowSource = strSQL
DoCmd.Close acForm, "Form1", acSaveYes
DoCmd.OpenForm "Form1"
