Jim,
I don't know this control specifically, but does it have a Paint() or Refresh() that you can explicitly call to cause it to repaint itself?
>I would like to give the user the ability to resize a map. However, when the form is resized, the map is not completely redrawn. It is only redrawn in the area of the map prior to re-sizing. If I click in the map area (either the drawn or the un-drawn area) the full map then appears.
