A while back we put together a web map by customizing the basic viewer template that was available at the time. I guess enough time has gone by that it is now the "classic viewer" http://www.arcgis.com/apps/OnePane/basicviewer/index.html
When I do anything that involves mouse position: info window click, measure tool, etc... the point that shows up on the map is offset to the left of the mouse cursor by ~ 10px. This is only in IE for me. The mouse lines up perfectly in Chrome and Firefox.
When I open our map in AGOL the measure tool also lines up perfectly even in IE so I conclude that there is something amiss in the basic viewer template.
Anybody know why or how to fix this?
