I am developing a dissector plugin to decode our company's wire-format for
development and debugging purposes. The dissector properly decodes and displays
information for the ports that the plugin automatically decodes as our
protocol, however when I use "Show Packet In New Window" it will reset the
Protocol Name and Protocol Info back to TCP while still displaying our decoded
information in the packet's payload as we click through the different packets
that contain our data.

If I use "Decode As" at this point to attempt to set the port manually back to
our protocol, the packet information will blink to our protocol for a second,
then back to TCP with TCP information (Again, while still displaying our
decoded protocol in the payload data).

Please note: This only happens when using the new interface (Wireshark.exe).
The legacy interface (Wireshark-gtk.exe) works perfectly.

I'm unsure of the proper way to debug this problem, and have not been able to
find similar issues with others. Has this been run into before, and are there
any tips I can get? Any information that I can give to help solve this issue?

The plugin is written in C.

Thanks!
