We've updated ArrowChat v1.0.6 to fix a problem with the buddy list showing a user multiple times in the buddy list for each photo the user had.
You only need to update if you are experiencing this issue.
How to patch:
1. Re-Download ArrowChat
2. Extract the file and rename includes/functions_receive_socialengine4.php to "functions_receive.php".
3. Back-up your existing functions_receive.php file on your server.
4. Place the new functions_receive.php file in the arrowchat/includes folder on your server.
