Yep. The problem is that mouse move are not always generated. It depends on 
the internal implementation of the widget in the toolkit.

What you can do is enabling a timer at Enter event, and disabling it at Leave 
event. Ecah timer the timer is triggered, just use the Mouse.ScreenX and 
Mouse.ScreenY properties to calculate where the cursor is on the GridView.

The right solution would be implementing a "Tracking" property in the Control 
class to tell Gambas that you want MouseMove events even if no mouse button is 
pressed.
