I have a workbook where two of the sheets have controls - one is a shape (basically a custom button) linked to a macro and a there is also a textbox linked to a cell. For years these have worked fine. However, now, when I save the workbook and reopen it, the button and the textbox have disappeared. If I recreate them they work fine but, as soon as I save and close, they disappear again when the workbook is reopened.
The display options for the workbook are already set to "for objects show: All", so this is not the issue.
