[mapguide-users] window open

Somebody please correct me if I'm wrong, but I just downloaded Maestro
and it appears that you can provide a link to display in the maptip.

Open the layer in Maestro, and on the right you will see a box named
"Link".  Use an expression similar to this one:
Concat(
           Concat('<a
href="http://www5.kingcounty.gov/kcgisreports/property_report.aspx?PIN='
,  PIN),  '">View Property Report for Parcel' 
)

To create a link in the maptip.  This expression strings together a url
with a variable "PIN" which is the Parcel Identification Number.

-Mark
