On iPhone/iPad, holding a button for more than half a second brings up an iPad menu for (Copy | Select | Select All).
Since a long press equals a right click, I guess maybe I need to suppress right click behavior on my symbols somehow?
If that's the issue, how do I prevent button Symbols from being selectable?
(Thanks everyone)
Someone else posted and example which illustrates the problem I'm having.
(The Rotate Left and Rotate Right buttons bring up that menu on iPhone or iPad if you hold them.)
