I recently updated to 3.7 and updated the appropriate widgets including the Robert's Identify widget. Everything is working fine on my machine but many other users of the viewer are unable to use the widget and upon activation other widgets perform poorly as well. Clearing the cache and rebooting the computers doesn't appear to help. I can't speak for the different browsers that are being used, but the most recent one I saw was Chrome, on my computer I am using Internet Explorer. This is incredibly hard to diagnose, I do see a number of entries in the log file that seems to point to the OOTB print widget being the issue though. I don't know a good way to post my log file but I will post what is available in the text document. It is set at 90 days so there is a lot of entries in it. Do I need to reboot the server perhaps?
