Derek, here's a copy of the map I'm working on that has the problem.
http://arcviewdev.uww.edu/javamap.html
(And before anyone says anything, yes, I'm aware of the errors with my data. They've been fixed on a more recent version)
Hopefully that will help.
I opened the map in chrome. Clicking on the poly's pops open the popup, no map moving ever. ??
It works in Chrome 13 and IE 8 but not in Firefox 5. Basically, you need to interact with the map first by zooming or panning before the onclick returns something. I had this problem in Flex and got around it by adding in an alert box in the initialization. Closing the alert box provided the map interaction necessary to allow the map click to work without panning or zooming.
To everyone else with a problem, what browser are you using?
I think this is an error in the api . If you switch to v2.4 it works crossbrowser
