Unwanted escapes when inserting html link

[Nestor Siu]

Hello,

I've been trying to insert an html link using Mozilla's html editor, 
which looks something like

<a href="http://www.bbb.com/script.cgi?var1=data1&var2=data2";>Some link</a>

However, whenever I try to do that, using the Insert->Link dialog box, 
the href string is automatically escaped to

  http://www.bbb.com/script.cgi?var1=data1&amp;var2=data2

and the cgi data 'put' fails.  Is there anyway to prevent my href from 
being "escaped" automatically?  The same problem also shows up when I 
want to, say, insert a counter .gif on the page, but the '&' are escaped 
to '&amp;' , causing the data 'put' to fail.

Thanks.
