Hey Jason...
Was there a resolution to this issue? My client and I both use the same version of Firefox and I can see and use the live edit, but she doesn't get the live edit window on her computer. She did at one time...even tried rebooting because she just hibernates her computer. No luck.
We've tried it on her computer in IE. She can get the live edit, but it doesn't let her add images, or select an image and change it. Also, when you try and cancel the image prop window, it doesn't close it. You have to refresh the page.
Appreciate your help.
