Appointments +, when activated, breaks admin functionality (dragging widgets, etc)

When I activate Appointments +, it breaks the admin side of wordpress. Once activated, I can no longer drag widgets, move blocks around on the dashboard, etc. There seems to be a javascript conflict. Using the console via google chrome, I found the error:

Uncaught TypeError: Object function (a,b){return new e.fn.init(a,b,h)} has no method 'widget'
jquery.multiselect.min.js:20

Uncaught TypeError: Object function (a,b){return new e.fn.init(a,b,h)} has no method 'widget'
load-scripts.php:8

Any ideas on what is happening here, and how I could fix it?

    Greetings nick_dugger,

    Welcome to WPMU DEV!

    It seems that you are spot on with the possibility of a conflict so lets prove it out and find out what is conflicting.

    It is time to go into full blown trouble shooting mode because it appears there may be some conflict there and one way to find out conclusively.

    Standard plugin trouble shooting protocol - first to switch to the Twenty Eleven/Twelve theme just long enough to check for the problem - if the problem still exists next involves deactivating all plugins except the plugin in question and then see if the issue still exists.

    If it does not, then you want to activate plugins one at a time testing in between to see if the issue returns. Even when you find one plugin, it may be in your interest to deactivate the problem plugin and continue testing the rest of the plugins to insure no others are also conflicting.

    You will know the conflict when the issue returns and which plugin(s) you activated that cause the issue.

    Please advise if there are any plugin conflicts and if so what the plugins are that are conflicting.

    Cheers, Joe
