Hey,
The small attached patch changes a pair of bits of the ToolTip class.
The first change is that calling SetToolTip for a control that already
shown its associated tooltip should make it visible _again_ if the mouse
pointer is inside its bounds.
The second one is that we were not updating fine the tooltip text when
SetToolTip was called for a control showing the tooltip at the moment;
it also should reset its internal timer (based on the MS behaviour).
Comments?
Carlos.
