Nope, that would be the latest *release* version, which would be 0.10. I’m using the latest *development* version that you can get from source forge. So yeah, that *could* be why my code isn’t working for you (though I don’t guarantee it).
There have been a lot of changes between the last release and the current development (like compatibility with PySide2, which is why I use the development). I keep wondering when they will make a new release, but it hasn’t happened yet. --- Israel Brewster Software Engineer Alaska Volcano Observatory Geophysical Institute - UAF 2156 Koyukuk Drive Fairbanks AK 99775-7320 Work: 907-474-5172 cell: 907-328-9145 > On Apr 11, 2020, at 10:06 AM, Daniele Dolci <[email protected]> wrote: > > I would assume I am on the latest version, I installed it today.
