I’ve got a simple WebToolBar with 5 buttons and only every other button does something on the Button Action Event.
So to test I’ve got MsgBox Item.Name on the button action, when I click Button 1 I get the message box, when I click Button 2 I get nothing, when I click Button 3 I get the message box and so on
I’m using Xojo on OS X and I’ve tested it in Chrome, Safari and Firebox same in all of them.
