Currently on the latest mac OS with a full size wired keyboard... same results on both airbook and imac which is a dual core i5. NOTE: Yes I have gone into mac keyboard settings and told it to use function keys as normal and not mac functions. Also NOTE: the key bindings and macros all work fine on everything EXCEPT the stanza bars... they will not switch to another bar without clicking on the arrows... it's only that function that won't work. I have found a way around this by using shortcut bar 2. This is the only way to have actions on more then one bar work. There is just no way to switch bars for me using keys or macros. At least my protections are always visible on Shortcut bar 2, so this will work for me.
