i am have a problem in mail new message 
when click and type in name for recipient it just sites there with a loading popup
even after 10 minutes still the same loading 

i had to deactivate this plug in as it cut off half the pm box after the update, i am waiting for it to be updated so it works in 1.6 any plans to do that soon

This plugin tested on Oxwall 1.6 and works OK. The plugin's demo site works on 1.6 version ( http://demo.oxpro.org ), so you can test it there.

The reason of the problem may be a conflict with other plugins.

Tammy,

I need your site url to test the issue. I can not help you without tests.
