Well--I installed the win32 version of SVN-19778 over my current 0.99.4
install and it works beautifully for the displaying text in TCP streams!

Thank you Joerg!

Excellent!

So if I download and install SVN-19778:
http://www.wireshark.org/download/automated/win32/wireshark-setup-0.99.4
-SVN-19778.exe

It will have this fix?

I've just committed 19773, which fixes this bug. As the fix is rather
trivial I'd like someone who knows that code to have a look at it and
verify that it doesn't have any negative side effects before I close the
bug.

Here it comes:

Please let me know whether the fix is OK so I may close the bug (I know
That it fixes the sample capture attached to 1043).
