Switching between Calendar View got into problem

Switching between Date/Week/Month and Date/Week/Month with Autopreivew in Calendar View got into problem.  It doesn't switch back to Date/Week/Month very often.  Sometimes i go back the Outlook Application and do some search or changing view on Calendar, then retry on the "Outlook on the Desktop", if lucky, I can switch back to Date/Week/Month view.

It's a great application, but if this switching view back and forth doesn't work, I could hardly trust on using it.

Hope this get solve shortly, many many thanks!!!
