Cannot even click the OK button on the preferences window, 'cause it's outside of the window and the window cannot be scaled or scrolled. Thread here:
Unable to save preferences Animate CC 2015.2 and 2015.3
Just posted this crazy bug at Adobe. This bug is causing the software to be worthless and useless.
If there is somebody out here knowing a way to work around this bug, please let me know. At the moment I cannot use the software at all because of this and I need it. Thanks!
Just in case other people wanting to know the answer on this one: there still is no hiDPI support in Adobe Animate CC. Workaround for now is putting Windows Display Settings to 100%.
As just answered here by Adobe: Re: Unable to save preferences Animate CC 2015.2 and 2015.3
