 Mapguide 2.2 & 2.4

 Sometimes (particularly doing a pan moving up the map) Firefox do not
 completely show the image that appears truncated or completely
 invisible.

 It is a redrawing issue because the image appears to be received
 correctly (through Firebug or its console) and moving around the
 window or doing other things that force a repaint solve the issue, aka
 the image is displayed fully and correctly.

 This issue is very annoying for users (it happens randomly) and is
 probably due to the two (or three) <img> that are updated at each pan,
 namely the map and the selection.
 It is also difficult to produce a simple test case for opening a bug
 against Firefox, since I think we are triggering some Firefox bug here
 with all that <img> manipulations.

 This is probably a Firefox bug, but a workaround on Mapguide side is
 welcome
