Wireshark-bugs: [Wireshark-bugs] [Bug 4485] UDP checksum validation does not function

I am missing a very important concept - the checksum is calculated when tshark
loads the data, not during capturing.

To add to the mix, I just recently upgraded from 0.99 to 1.2.5.  I believe it
used to validate udp checksum when displaying.

I assume adding "udp.check_checksum: TRUE" into a preference file will save me
from having to type this option every time I want to display a frame?
