This one pops up an error message I've never seen before in Windows 
Firefox 1.04:
   "A script on this page is causing Mozilla to run slowly.  If it 
continues to run, your computer may become unresponsive."  OK or Cancel 
.  When I hit "Cancel" to dismiss the message, the track was drawn 
normally. 

IE 6.0.2800.1106C produced the identical results.  

Opera 8.01 worked perfectly with no messages.




Initially, both the URLs below didn't work at all because of the space 
between "cgi?" and "call=". .  This caused the Thunderbird email client 
to only turn the first half into a live link. After copying and pasting 
into the browsers and then closing up the space before hitting "Go",   I 
got the following results for these two URLs.

After closing up the space, the first one produced the background map 
but no track at all in IE.  It worked normally in both Firefox 1.04 and 
Opera 8.01.  The track seems to include a straight line "hyperjump" 
apparently due to one bad data point.


The second one works properly in all three browsers.
