Within the past week or so, I've been getting an error when I try to insert an image or link when I'm running our Jive instance (version 4.5.5) on Chrome (version 21.0.1180.89) on a PC. See attachment for what happens. Works fine on IE9, when it isn't crashing, that is! Any suggestions, other than upgrading our version of Jive? Or why this just started happening?
