When I run e.g. editra and type in the PyShell tab I see a "refresh
flicker" on each key stroke
This is a known problem, and probably in the C++ code. I haven't tried to track it down yet myself though.
and when I run demo.py I can only run one
demo before it hangs -
Hmmm... It just happened here too. I'll see if I can find out what's going on.
I thought there is still a problem on my side - it looks like it is something generic.
You didn't see/get any exception either?
btw what is the trick to see the console window
when one runs the demo on Ubuntu?
If you mean a terminal/command-line window then you can just run the demo from an existing terminal.
Thanks I thought so, but as I couldn't see any exceptions when running the demo I wondered if one had to do anything special.
Otherwise you can get a plain PyShell with F5, a WIT with F6, or turn on the stdout redirection with an option in the File menu, (which should be moved to the Options menu...)
It looks like there may be a bug in freeze/thaw somewhere, the main panel in the demo is not getting fully thawed out after the second sample selection so although a new sample is selected and loaded the main panel and its children are not being repainted because they are still frozen.
