HINTS-ON* - Controls how long the mouse must remain stationary over a bitmap button before displaying its pop-up hint. For a description of pop-up hints, see Book 2, Chapter 3, section 3.8.4 . Set this variable to the number of hundredths of a second that the mouse must be stationary. The default value is "75" (three quarters of a second). If you set this variable to "0", pop-up hints will not be displayed. Setting this variable to "1" or "2" is not recommended because it may result in the pop-up hint being displayed while the mouse is moving across the button face (because the mouse motion events may occur less than 0.02 seconds apart).
