I am using Flexviewer 3.6 & ArcGIS Server 10.1. I have a map containing the Navigation widget and the Edit widget. If not editing all nav functions work, when I open the the Edit widget, the zoom-in/zoom-out buttons in the nav widget are greyed out and cannot be activated. When I close the Edit widget it all works again. Both widgets are ESRI's out of the box, unmodified. Any ideas (and am I the only one with this problem)?
