Momentary beachball issue

Has anyone experienced in CB 10.5, while working on a session you are doing your normal editing, selecting waveforms, jumping around the file, calling up plugs etc, and you get a momentary beachball when doing so?

Thank you

Has anyone experienced spending so much trouble to get an account on forums just to post rubbish, actually ever went to a beach? To play ball?

May I ask why my inquiry is rubbish?
