Subform prevents undo problem

I have a form with a tabctl and about 8 pages. Most of the pages display various fields from a record (customer data related page, financial data requirements page, etc). A few pages display a subform. to add/edit data on a record, the user clicks an edit button. to cancel, the user clicks an undo button. Works fine to undo all changes to all pages UNLESS/EXCEPT if the user happens to have clicked on a tab that has a subform. Appears that the process of clicking through a subform saves the changes.

Is there a way to prevent this, and allow all changes to be undone even if a page with a subform is clicked?

I'm baffled

Thanks
