<p class=MsoNormal>Are you issuing the script from a command?<br>
<br>
If you want to do this all the time (regardless of what the user has done), you
must load the script with the solution.<br>
If your map is embedded in another page, you can load the script there, and
change "var map = parent.parent.mapFrame;" to point to the correct
frame.<br>
If it is just the basic layout, you can try to put it in the page that loads in
the taskpane (but beware that the document gets unloaded if the user
navigates).<br>
As a last resort, you can embed the script in the viewerfiles.<br>
<br>
In case you can use the embedded map approach, you should place the following
line after the "try {":<br>
map = document.getElementById('<insert iframe/frame id>').GetMapFrame()<br>
<br>
