My short-term solution (on Yosemite) has been to use Chrome or Firefox for my work in FileMaker Community. It's my subjective impression that Jive performs more consistently in Chrome and Firefox than in Safari.
I realize that this is not a very satisfying solution, but it's what I'm doing at the moment.
Thanks but I will wait for you (the collective FMI you) to get this fixed.
I run into those types of issues constantly, Mark. No clicks responding on the Inbox page, menus not loading, etc. I use Chrome almost exclusively. Never have problem anywhere except on this site.
Most often a page refresh gets things working for a few hours.
