Ctrl-Tab only works one way for me, i.e. it won't toggle between the two, just switches to one and then Ctrl-Tab does nothing. 
Have you tried going to the "Lenses" drop down menu, click on "None" even if "None" is already checked.
I usually have to do this to get my Ctrl-TAB working properly, ever since the Lenses feature was introduced.
Thanks, that seems to help. Although, I had 'None' already selected in Lenses, so selected a different lens and it made things work! Another way I got it to 'work' was to go into each project and close down any piano roll, console, views, etc. first. Methinks a bug may be lurking here, or at least some inconsistent behaviour.
