I have written a Manipulate function that takes a list of text values as options for the user to select, and presents them in a PopupMenu control.
When I first press Shift + Enter, I get the very cryptic error message...
An improper nine patch image input option was encountered.
Thereafter, it works fine.
I cannot seem to find any information on this error message. Does anyone know what it means?
My notebook is attached.
Thanks in advance,
