- Thread-topic: Blue highlight on NSMenuItems stops appearing
I am seeing a strange problem in a new app, where the standard blue highlight which appears when mousing over NSMenuItems in NSMenus will suddenly stop appearing in the app. So there is no longer visible feedback about which menu item the mouse is over in any of the menus (including the main menu and menus of popup buttons). Sometimes the highlight will eventually come back after clicking around in the app and doing various things, but other times it's just plain gone.
To learn more, I setup a delegate to one NSMenu and implemented "menu: willHighlightItem:". I wanted to see if this was still fired once the highlights stopped visibly showing up. It is fired, so obviously the proper mouseover/highlight event is being registered. This suggests to me that there's instead some sort of drawing/display issue with the highlight. The fact that it affects every menu in the app has got to mean something....
Anybody have any ideas?
thanks,
Craig
