I gave my mate a text this morning (UK) who is an Adobe freak and of course runs Mac's. He updated and states that plenty people are having problems with cursors disappearing and docs taken ages to save and he suffered the latter. He pointed me in the direction to here: http://helpx.adobe.com/drive/kb/open...lower-mac.html Had a look at it but this refers only to Adobe Drive and the saving problem so don't think that helps you. I would go along with Mike's statement and do a reinstall which is a right pain.
