 After starting a Fusion map application, the visibility of the map layers
 and the status in the legend are in synch, that is, all map layers that
 are checked in the legend and only these are visible in the map. However,
 after unchecking a map layer, it remains visible in the map, if checked it
 again, it's gone from the map only to reappear when unchecking it.

 I am using MapServer 5.something (sorry, can't tell which version
 exactly).

 It may be in the functions show() and hide() of
 Fusion.Maps.MapServer.Layer and Fusion.Maps.MapServer.Group. In the four
 functions, redrawing of the map is triggered through showLayer(..),
 hideLayer(..) and showGroup(..), hideGroup(..), respectively. Then,
 statements that change the value of the visibility flag follow. I suspect
 that the latter statement should occur before (!) the calls showLayer(..),
 etc. I tested it, and it fixed the problem.
