The same here... But with Conectiva Linux. SuSE is Conectiva's partner
on the United Linux Consortium.

I haven't tried using Unicode. My applications still don't need it and
I've seen lots of reports about it not working properly.

It doesn't happen here. Since I'm Brazilian I use a lot of chars that
are not 7 bit ASCII (á, é, ç, ã, õ, etc.) in a lot of places :-) No
crashes due to that, except with an old version of wxGlade on
Windows, where my parter couldn't open / create a file with "special"
chars on titles and notebook tabs: it crashed there. On the other
hand, it worked perfectly on Linux and on the running application, so
after he finished the application, he used my Linux box to add all
the missing stuff (then he learnt about sed & cia. with me).

I agree with you on that one. I haven't insisted much on the GTK2
stuff though.

Could you please say more on the way the other tools are used? I
adapted better with wxPython than Tkinter here... Probably I would
look after Tkinter different today and I would even try it a little
more based on several comments here, but then theres wxPython and it
is solving my problems very nicely.

Which widgets you missed there?

It would be very good if wxPython was more python centric instead of
trying to be more like wxWindows. But I guess that people who
prototype in wxPython and then convert some parts (or all) of their
application to C++ wouldn't like such a change... 

There's "equilibrium" here, and messing with that would be
dangerous :-) Another advantage is that wxWindows is already there
and it works. It would be a shame not to benefit from that. 


Since you mentioned CGIs, don't you like using Python for that? 


Be seeing you,
