Selecting text or trying to type is very slow. The problem just started the other day after Animate updated to version 20. I also could not export a movie with an alpha channel so I reverted back to 19.21. Alpha channel works now but the text is still super slow. Also, something I thought was odd... It takes a few seconds to open Preferences.
