In regards to suspected incompatibility with some other addon, Chatmanager works fine for me with my other addons, CTRA, Telo's, Auctioneer, Atlas, and Decursive. It also seems to be working fine for my guildmates who use various CTmod and Titan installs.
Could you tell me what other addons you are using? I could then try and have a look into what ones might be causing this problem (or which one might be exposing a flaw in my code
).
Thanks!
