Several issues with menus not working in adobe animate

My school has adobe cc and I am using adobe animate as a relatively new user, with extensive experience with illustrator and photoshop.

I cannot save or close animate files except by using save all.  None of the buttons work on closing menus and some options don't work within animate e.g. tagged colour button menu opens but I can't change options - I just have to escape each time.

I am also having problems closing animate - continually have to go to task manager...

These are serious issues - is this common?

I am using a pc with windows 7..

Regards,

Steve
