Hi @Yueh17,
This seems a weird behavior since the docks are not inherently closable (as seen in the screenshot, there's no way to toggle it manually from the dashboard). It might be some qt bug I guess.
A workaround is to reset the state of the dashboard by deleting the file artiq_dashboard_{server}_{port}.pyon
.
For safety make sure you backup the original state file before deleting it.
To find the location of the file, from the command line:
python -c "from artiq.tools import get_user_config_dir; print(get_user_config_dir())"
Re-opening the dashboard will reset it to default state, hopefully with the shortcuts dock visible.
The dashboard will generate a new state file upon closing it.
Hope this helps. Please keep us posted.
