Note, in the following post, a user shared her GUIDE GUI files (link below). When I opened the GUIDE figure in r2019b and tried to change the Visible propery of the GUI figure from the properties inspector window, an error appeared preventing me from making the change. The error pertained to the AnnotationPane handle. A screenshot of the error is included in the link below. That same process in r2019a did not result in an error.
This problem can be reproduced using the attachments in my question above by following these steps.
- From r2019b, open the PanelAxesGUI_demo in GUIDE
- Right click the Panel and select property inspector
- Change the "Visible" property to "off" which results in the error below.
- Now, from r2019a, open the PanelAxesGUI_demo_r2019a in GUIDE
- Follow steps 2 & 3 above; this time, no error.
