Can't open file with blockly / primtux (ubuntu based)

[polochon777]

Hello, I can't open a previously saved .aesl program with blockly. The "open" button do nothing, and drag & drop from file explorer doesn't work. This is annoying, the kids cannot save their program and reuse it the next programming session.

Note that the save button automatically save an "untitled.aesl" file in the ~/Downloads directory

OS is ubuntu 20.04LTS Thymio suite 2.3.2-c408856c

Thanks a lot Polochon
