In my application I use a lot of TAdvStringGrid components and a few of them require balloon hints. They all used to work fine, but something has changed and now none of them work.
If I create a new project with a grid on it and enable the balloon hints, the OnCellBalloon event is called and the balloon hint shows correctly.
If I then copy and paste that working grid in the real application, the hints for it don't work either. There must be something about my application that is interfering with them. Any ideas?
