Note 53: If you have an older version of Windows, you'll have to enable the balloon hint by turning on the EnableBalloonTips key under Software\Microsoft\Windows\ CurrentVersion\Explorer\Advanced of the current user section of the registry.

This is a comment to the use of the balloon hint features (page 131) of the new TrayIcon component of the VCL, which can be setup as in the following DFM fragment:

object TrayIcon1: TTrayIcon
 BalloonHint = 'sample balloon hint'
 BalloonTitle = 'hi'
 BalloonTimeout = 1000
 BalloonFlags = bfInfo
end
