A long time ago I posted about an issue I had with CB 1.1 and the fact that field delimiters were always showing on the profile even when configured not to. I still have this problem with 1.2 RC3 but the old fix does not work since this bit of code has been majorly reworked. I have an alternate fix for 1.2 RC3 which I've posted in the old thread:
