Hi,
First off I would like to say this is an excellent plugin and thanks for your hard work and continuing support and development.
I have found a clash with another plugin which stopped me from being able to drag and drop menu items in SETTINGS – PixoPoint Menu – Home
I tested in FF, IE, Chrome & Safari and experienced the same issue.
I have disabled -> enabled the plugin 4 times now, testing each time and experience the same issue so can comfortably say it is this plugin at fault.
The Plugin is called: WP Events Calendar

thanks,
