[QGIS-Developer] Need help troubleshooting Browser Panel freezing QGIS

Fri Oct 9 00:19:22 PDT 2020

And besides that, have a look in the Settings/Data Sources, there are some settings related to the way the browser scans for item (Basic or Full scan), please try out that one too... And if then still failing, create a good issue, with how to reproduce and versions of everything, your setup (is your profile on the network disks) etc? (though I realize that it is hard to see what is going one, but maybe you can do some remote desktop thing? Or s screencast?
Can you check/disable your virusscanners?

Regards,

Richard Duivenvoorde

Seeing that DB Manager may be discontinued, and several of its functionalities are being moved to the Browser Panel, I tried to figure out what is wrong with it.

I am pretty sure this is not limited to my computer: I provide training to other staff, and they all have the same problem (both OSGeo4W-advanced and standalone installations).
