Startup issues with python 3.12.6 win (64-bit)

[sronline]

When trying the application with python 3.12.6 win (64-bit) I had the following issues:

1. wxPython could not be installed. Solution: use snapshot-build

pip install -U --pre -f https://wxpython.org/Phoenix/snapshot-builds wxPython

2. asyncore could not be found, deprecated. Solution: install pyasyncore

pip install pyasyncore

3. deprecated warnings and crash at sizer.AddGrowableRow. Solution: attached patch
