I'm having the exact same problem mentioned earlier with the color codes appearing next to my message string in a bind. (Works fine if I manually type it into the chat box as a slash command and hit Enter.)
I don't even have the border color set on my binds. For example, my bind to the 'sysrq' key looks something like this:
sysrq "say <color #BFCFFE><bgcolor #0033CC>Gather for Recovery Aura!$$ bind_load_file C:\CoXBinds\NextBind.txt"
Everything works fine with the exception of the chat bubble colors as mentioned. Any other ideas?
