Moving the cursor from one control to another keeps the active tooltip visible and changes only the text. Instead we should hide the tooltip onleave. Pascal knows three parameters for tooltip timings: HintHidePause: time interval to wait before hiding the Help Hint if the mouse has not moved from the control or menu item HintPause: time interval that passes before the control's Help Hint appears when the user places the mouse pointer on a control or menu item HintShortPause: time period to wait before bringing up a Hint if another Hint has already been shown (https://docwiki.embarcadero.com/Libraries/Athens/en/Vcl.Forms.TApplication.Hint)
