The acFormHints component applies the balloon hints for your controls instead of regular, rectangular hints. Balloon hints are displayed in a cartoon-style "balloon" with rounded corners and a stem pointing to the tool. They can be either single- or multi-line. You can specify the default balloon direction, text alignment and degree of transparency and other features that affect on hint appearance. One component changes appearance for all hints in entire application.  
new! You can select the style of hint dynamically at run-time using OnShowHint event. For example you can select the cartoon-style hints for some certain controls but standard "boxy" style for all other controls.  
new! Now you can use MaxWidth property to control the maximum width of balloon and wrap the long strings to next line.
