Could reproduce it here, but it is _very_ hard to pinpoint where this

Should be no problem now that you don't have to use stunnel anymore.

Well, nevermind, then :p

Done, too. Mine atm for example is:

In another thread there was a discussion about letting the user choose 
quote characters.
See prefs (last tab) and _enable_ @ as a quote character and see the 
paragraph below.

@ Description
@ ----------------
@ BUCK, a richly textured and visually stunning film, follows Buck 
Brannaman from his abusive childhood to his phenomenally successful 
approach to horses. A real-life horse-whisperer , he eschews the violence 
of his upbringing and teaches people to communicate with their horses 
through leadership and sensitivity, not punishment. Buck possesses near 
magical abilities as he dramatically transforms horses - and people - 
with his understanding, compassion and respect. A truly American story 
about an unsung hero and one of the most successful documentaries of the 
year, BUCK is about an ordinary man who has made an extraordinary life 
despite tremendous odds.

--> Also be sure to check my "tabs" branch. It works, but doesn't handle 
the "hanging" of pan when loading a new group as that must be fixed 

I'll fix the other "requests" when I have the time, but for example more 
threading is _really_ needed, the code as it is now is using threads, but 
only _one_ at a time for example for one TaskArticle (i.e. one download). 
My upload code uses multiple "threads" (class instances.)
I'll modify the source so there are multiple downloads and encoder/
decoders working simultaneously, but this means a little overhaul of 
pan's inner core.
It can be done, but I'll take some time to test it thoroughly.
