Pressing CTRL-ALT-I with the 4.2.2 demo and 4.2.2 installed… I get this error:

well, what about

        if obj.GetChildren():
            count = len([c for c in obj.GetChildren() if not c.IsTopLevel()])
        else:
            count = 0

on line 659 of inspection.py (never used it so far) :rofl:

You are probably using Python >= 3.13.1 which had a modification in byte code generation.

It has been fixed in the wxPython repository:

You need to use an older Python version or try a recent wxPython snapshot build from Index of /Phoenix/snapshot-builds

Thanks Dietmar,
I posted on Github issues too, and found that using a pre-release of version 4.2.3 fixes the issue!

thanks again for your thoughts!

Another option to get a recent version if you prefer using pypi is to use wxPythonMeticy.
