causes for losing COL_PROTOCOL or COL_INFO data

[John Dill <John.Dill () greenfieldeng com>]

I'm setting the column fields and they appear to be set fine when I first open Wireshark, but when I apply a packet 
filter, I lose information from the fields even though it appears that I'm still calling the same col_* functions in 
the dissection.  Then when I remove the filter expression, and the COL_INFO I set is still missing.  Is there a usual 
cause for this behavior?  I can't seem to discover what's causing it.



Thanks,

John D.
