In the latest version of Chrome (58), when double clicking on an image in an editor (FTI part, Email editor, etc) the fields to edit the image will appear blank, lacking the image information. You may also try to update a hyperlink, but are unable to replace it with a new link. This may also occur in Internet Explorer 11.
NetCommunity uses a WYSIWIG editor from a 3rd party, TinyMCE. The TincyMCE editor does not appear to be fully compatible with Chrome 58 or later versions of Internet explorer 11. Various behaviors with inserting images or editing links are occurring.
We are currently evaluating this issue and will update this article when we have more information. In the interim, we suggest using Firefox. In many cases it is also possible to edit the image in Chrome v58 if you click once on the image and slightly drag it, after which you can select and resize the image without breaking the way it does with a double-click.
