I have to respectfully decline trying to modify that widget. I hope you can find a way to get that working if that is truly your desire.
If you are interested, I did make a few modifications to Earthquake Map 3; now it has four preset map sizes, controls are hidden so the display is cleaner (toggle w/middle-click), expanded the context menu options (which already offers more options for information than most other versions I have tried).
Perhaps another forum member may be interested in resurrecting that Yahoo Widget.
Dear eclectic-tech, well, thanks anyway for looking at this, and providing the information about Brian's widget.
May I ask, do you know of anyone on the site who might be willing to help? Thank you again.
