Hi,
I'm trying out a trial version of Arrowchat and it all seems fine except one thing - when you send a smiley, the sender can see the smiley fine, however the recipient sees a broken image. Inspecting the image shows that the path is wrong - it's missing a slash. An example:
/arrowchat/themesnew_facebook_full/images/smilies/smiley.gif
There should be a slash between themes and new_facebook_full.
