ScriptUi listbox items missing check marks when preceeded by a dialog window
I have been having a persistent issue that I have only just been able to reproduce with simple enough code to post. What I am finding is that check marks in list items do not show up if there was a dialog box immediately preceding them (I am running Mac OS and have not tested on Windows yet)
file = File.openDialog();
var w = new Window('dialog', undefined, undefined, {
resizeable: true
});
var myList = w.add ('listbox');
myList.preferredSize = [300, 400];
var item;
for (var i = 0; i < 200; i ++) {
item = myList.add('Item', i);
item.checked = true;
}
w.onResizing = w.onResize = function() {
this.layout.resize();
}
w.show ();
If I click in the list box, scroll or resize the window the items redraw and the check boxes all of a sudden appear!

If anybody can think of some ideas to fix this I would appreciate the help.
