I also have important bugs with latest yosemite os x 10.10.1 and even 10.10.2 that I have tried today.
I made a post on olivier truc 11 janv. 2015 09:36 "important bugs".
I have the latest version of edge animate and a very recent mac desktop.
It is really a problem coming from edge animate and I can't find any information on how adobe works on this and when it will be solved. Disappointing and upsetting because in the meantime you pay your membership.
