Why are some maps not displayed, namely those from MapBlast showing a lot of stations or a lot of points?
You are probably currently using Microsoft’s Internet Explorer v 6.0 and up. MS unlilaterally shortened the length of URL it will accept (because their web servers have a lot of security holes, and web exploits almost always depend on long URLs to overflow buffers). MapBlast URLs get very long when a lot of stations or tracking points are to be displayed on the map, so at some point, the URL gets so long that IE 6+ will reject it. As far as I’m aware, no other browser does this, nor did IE prior to version 6.0. I will not decrease the utility of findU to support this “feature” of IE. Some CGIs, like track1.cgi, can be made to work by decreasing the length of time plotted, or like map-near by decreasing cnt. Others cannot be made to work, if you want to use them you need to get a better browser, I recommend Safari for the Mac, and Opera and FireFox for all platforms.
