Hi, when I click the Monitor Center, nothing happens. I have tried restarting the computer, reinstalling PsychoPy, uninstall-restart-reinstall, I even upgraded to the new version. The original bug started on v 1.82, upgrading to 1.85 did not help. There’s this error message every time I click the monitor center icon:
Traceback (most recent call last):

This started happening after I tried to set up a new monitor in the Monitor Center. I closed the monitor center before finishing setting up the monitor and it won’t open again. Reinstalling the program does not help - but I also found out that PsychoPy keeps some of it’s settings even after reinstall (when I change the default view from Coder to Builder for example, then reinstall, the porgram will open in Builer again, and vice versa).
This makes me feel that PsychoPy keeps some data on the computer even after uninstalling. And that closing the Monitor Center before finishing monitor setup properly might have screwed up someihing in that data, which is preventing the Monitor Center from opening.
Thank you for any help.
