Hey Frank,
I did not think of using a popup menu for file selection. (partically
because I had in mind to make a version of Yves playlist using a listbox
and scrollbar, so I did not think of the possibility of using a popup.)
so I suppose a switch to turn on returning symbols or returning index
values would be best. That way when using the menu to select things like
gem window messages you could use selects and not have to fill an
[index] object with symbols.
Is [index] the best way to compare symbols?
Thanks for the feedback.
