Understandable, and I agree. Non-positional links now serve almost the
same purpose, but they do have the advantage of offloading the
additional sequence metadata into another file, rather than stuffing it
all into the description line.

Normally, this is not necessary. Are you talking about when the applet
tag is generated within a Perl CGI script ? (then all $ within double
quoted strings must be escaped)

If you escape the '$' and set the debug flag (param name="debug"
value="true") then jalviewLite raises an error because it cannot parse
the value of the linkURL_2 as a valid sequence ID regex link (in this
case it is because the /=$ cannot be found).

I'll look forward to it!

thanks for your patience, again...
