[fusion-users] Hiding layers and clearing the selection at the same time.

[Paul Spencer]

Ari,

I would try reversing the logic and hide the layers first with no  
redraw, then clear the selection (which triggers a redraw).  drawMap  
should then pick up the changes in the layer visibility.

Cheers

Paul
