DOpus has become unuseably SLOW over recent weeks to update the folder

In the past I updated to V10 & V11, but have always used V9. In recent weeks, the response has been unbearably slow to update the folder tree, navigate, etc. I updated to V11 - no change. I then paid to go to V12 - no change. With this current behavior, DOpus is totally unuseable. Help.

Does it make a difference if you turn off the folder tree?

Is it only slow the first time a folder is loaded, or every time?

If it's every time, what happens for the same folder in File Explorer?


Slowdowns when reading folders are often caused by shell extensions something else has installed:
