We have some Mac-users who have reported issues with right-clicking.
They want to show the context menus by using the Control-click method, and this does not work within the GoJS diagram.
Using this method in the browsers main area shows the browsers context-menu correctly, but not inside the GoJS diagram.
Is there any way GoJS can trap this Control-click and interpret it as right-click?
We are investigating this and will get back to you soon.
I believe this has been addressed in version 1.3, 1.3 beta 1.
Thank you for the update, walter.
