Messages drag drop does not seem to work when contextmenu plugin is enabled.
Yep there was one bit of refactoring which didn't get moved correctly, I've fixed it now thanks.
Also I made sure display_next doesn't confuse it. I would be interested to hear what the issue is relating to your scheduled_sending plugin. I think contextmenu should be able to play nicely with other plugins!
Thanks very much for testing it so carefully.
