Comment(by yangte):

 When the map has base layer group, the ajaxviewer will hide the dynamic
 map image div first.
 {{{
 function HideMapImage()
 {
     if(!HasVisibleBaseGroups())
         return;
     document.getElementById("img1").style.display = "none";
 }
 }}}

 In the code for IE/Firefox, the Ajax viewer will unhide the map image div:

 {{{
 function OnMapOverlayImageLoaded(e)
 {
 ...
 var imgdiv = document.getElementById("img1");
 ...
     {
         img.src = overlayimg.src;
         img.style.position = "absolute";
         img.style.visibility = "visible";
         img.style.width = mapDevW;
         img.style.height = mapDevH;
         img.style.left = 0;
         img.style.top = 0;
     }
     imgdiv.style.display = "block";
 ...
 }
 }}}

 However, in the code for !Chrome/Safari, someone forgot to unhide the map
 image div:

 {{{
 function OnAlternateImageLoaded()
 {
 ...
     // Show the newly loaded image
     img.style.position = "absolute";
     img.style.visibility = "visible";
     img.style.width = mapDevW;
     img.style.height = mapDevH;
     img.style.left = 0;
     img.style.top = 0;
  ...
 }
 }}}

 so the solution is to simply unhide the div.
