In game text chat broken

same.  i run full screen mode here.   I can pull up chat, but not able to type at all.

Last night i put an old saveprofile back in config directory and relaunched and it worked, but today it is broke again.

Same. Broke since winter offensive, hot patch didnt fix it.

I'm going to try that in a few minutes.  I'll let you know if it fixes it, even temporarily.

It is impossible because such a major feature being broken would have been caught in Labs or something before the holiday
