Solving this issue requires to code the css filter effect and detect Microsoft Edge.
Obsolescence. Take it easy.
You won't see any updates to Edge Animate's UI or any other aspect of the program. You may be able to mess with the code it outputs to solve any problems - but that's it.
Sorry Joel! Even though the initial message when they stop development said that there might be some update if something drastic happened, I do not think it will actually happen because all the dev people have been scattered around the company. i am still sad because EA was a great product especially for DOM project. Animate CC is CANVAS and does not fill the same purpose.
