I have installed Python 2.5, PyMUI and PIL 1.1.7 (the last is not required to run helloworld.py script). When I try to run the script, I'm getting the following error:

Work:Dev> python2.5 helloworld.py
Traceback (most recent call last):
File "helloworld.py", line 16, in <module>
win.Notify('CloseRequest', True, lambda e: app.Quit())
File "/Libs/python2.5/site-packages/pymui/_core.py", line 812, in Notify
AssertionError
Work:Dev>

Any ideas what could be causing this? Have I missed something in the installation process? Need some help to get me going with Python...

It's a typical Python/PyMUI API incompatibility. Just ensure yourself you're running most recent pymui (i.e. definitely not one off this very site).

You have to source the distributions from Yomgui's site directly. Then eventually try some combinations if this doesn't help.

After that, can anyone upload the working combination here, or to MorphOS-files, or something?

I have already installed PyMUI 0.4 from Yomgui's site, download from here:
http://yellowblue.free.fr/yiki/doku.php/en:dev:pymui:start

The installation is in SYS:Libs/python2.5/site-packages/pymui/
I can't see anything obviously wrong with the installation on my machine...

The script I'm trying to run is the example from Yomgui, here:

As I said, maybe you ought to try some builds' combination.

Or ask Yomgui directly. He's here around. Guess I saw him posting some two days ago. He is pretty busy though and an active guy so might not have noticed that incompatibility.

Like... try Python2.4 or any other available. Some combination MUST work (it worked for me) and then you can think of porting upwards or towards more up-date versions.

After some testing, as suggested, I have found what works and what not...

PyMUI 0.4 r222 does not work with the final Python 2.5.4 r129 or r101 despite what is said in installation instructions or on MorphOS Files archive.
PyMUI 0.3 r162 is working with any of the two final releases.

I did not try PyMUI 0.4 or 0.3 with Python 2.4 because I may want to use Python Imaging Library which aparently works only with 2.5.
