The function file associated with the GUI includes initialization code that
MUST run before you interact with the GUI. Double-clicking the figure file
bypasses the function file and does not execute that initialization code.
ALWAYS start a GUIDE-generated GUI by executing the function file, NOT by
opening the figure.

Note the first part of that sentence. The GUI is only fully initialized once
the associated function file executes.
