I have an Eltima Virtual Serial Port ActiveX Control on a Access form in Office 2013 under Windows 10. All the form does is open the control to COM1 on Form Load and then close it on Form Unload. If I open and close the form normally there is no problem, but if I open the form to Form View and then right click on the title bar and select Design View, I get Error 2467 - Object closed or doesn't exist. However, if I open the form in Design View from the start, there is no such error. Only when going from Form View to Design View directly. What is causing this error?
