Re: [Pythoncard-users] Problem with Resource Editor on Debian / Kubuntu

[Christoph S. <cs...@bo...>]

Kevin,

Thanks a lot for your detailed reply. Actually its not that big problem,
since the GUI design is not the biggest deal and i am still able to code
and test on linux, just when adjustements to the GUI are necessary I'll
connect to a nearby Terminal Server and will do the adjustements there.
Also I thought I exhausted google on this matter but I overlooked the
most obvious source of information: local docs ;-)

Cheers,
Christoph
