Comment # 2 on bug 11702 from Jim Young

Hello Carsten,

Did you by any chance first open and then close a capture file before leaving
Wireshark in the background?

I'm seeing a set a new set of messages logged once per second to the console[1]
after I close a capture file.

The spark lines do not update after I have closed the capture file.

I do not recall seeing these messages clocked out before today.  I see this on
botj master and on the same version you tested.  I'm let the version you tested
run on my Windows 8.1 system and it crashed:

<Wireshark crashed at this point>

[1] - I have modified my Window's Wireshark preferences to enable the console
always and to enable debugging log levels.

> ####### User Interface ########

If I launch Wireshark directly from a CMD shell (something I do about 50% of
the time on Windows) then the log messages are written directly to the CMD
shell window and no console window is created.
