How does it open the second gui ?

[Riya]

by using 'open gui2.fig'

[Walter Roberson]

That will not work. See my Answer.

[Walter Roberson]

If you attempt to open a second GUI by using openfig(), then the initialization code associated with the second GUI is not run, so it will not have a proper "handles" structure. To open a second GUI you should start its .m file.

[Walter Roberson]

This applies to open() as well, which will call openfig() for .fig files.
