Hi,
I have an issue with Python: scripts are not saved.
If I write a new Python script, save it and close the window. The script is not there anymore when I reopen it. There is no problem wit EZ scripts and JavaScripts
Please Let me know if it helped ?
:p

OK, so after some tests, it seems to be related to the choice of the default script edit mode.
If I install ARC and choose Python as default, it works and Python scripts are saved. If I install ARC with any other language, Python scripts are not saved.
And finally, if I want to choose Python as default script edit mode after install, I can't because Python is not available.
I’ll take a look and update in the ARC beta channel
I downloaded ARC ARC Beta 2020.05.01.00
