ArrowChat breaks BuddyPress messages compose page

[MRF273]

Hi Guys
I'm using ArrowChat with Paid Memberships Pro and a BiuddyPress theme (Aardvark) and if ArrowChat is enabled then the message compose page (i.e. /members/xxx/messages/compose/) in Buddypress breaks. This is the javascript error in the console.

Is there a way to selectively disable ArrowChat on this page or work around this error?
