Using the deprecated FullCalendar display plugin prevents use of Ajax

I have the problem where if you drag and event in the calendar, I get a message saying my changes have been saved....but when I switch to the week or day view or to another month of the year and then go back to the events that I drug they appear to have reverted back to there original state. However if you refresh the page, the changes are then reflected.

My apologies if this becomes another "duplicate" on this topic. I have searched through almost all the issues with "drag" and this is my analysis and I am still having the issue.

The above submitted issues appear to be the same topic...however they are a bit dated at this point and while using the latest and greatest I still have this issue. Also I see a lot of mention in the http://drupal.org/node/971034 issue about the "Use Ajax" option in the fullcallendar view advanced options. I however can not find this option (see attached views image) and was wondering if it had been removed from Views. If that is the case what is the configuration I should use to get the expected functionality?

Configuration:

• FullCalendar 7.x-2.0-beta2
• Views 7.x-3.1
• CTools 7.x-1.0-rc1
• Date 7.x-2.0-rc1

Thank you for the help.
