Didn't freeze talk as i actually use it. I froze with titanium. Here's the list:
Amazon Kindle Amazon mp3
Google play movies
Go to meeting
My Verizon mobile
Universal inbox (both apps)
Vcast media manager
Yahoo Authenticator (defrosted because it's connected to contacts)
Although the fact that your chat is still working in wwf while suddenly not working in hwf makes me think it might be app-specific and unrelated to the freezing... try reinstalling hwf??
I would imagine they'd use the same protocol for both apps since the chat function is virtually identical. One would think that if a frozen app breaks the chat for one app, it would break the chat for the second as well.
