RE: LAS support for Mac OSX

["McCann, Mike" <mccann@xxxxxxxxx>]

Lynn,

Thanks for the info.  I feel that we're getting close.  We installed the
new Netscape and MRJ plugin and removed the JavaScipt checks.  As the 
page is loading (from our LAS 5.0 server) this message pops up:

 	"Undefined: undefined[object event]"

and the site cannot be used.

Did you have to do anything else with your server?  Also, with Netscape
and the MRJ plugin I'd think that the applet at:

http://tmap.pmel.noaa.gov/~callahan/JAVA/map_v3.0/LiveMap_v3.0.html

should work.  After I draw a new region in the applet Netscape 6.2.1 
crashes without showing any error messages.   Any clues?

TIA,
Mike
