I read and write through a translator, so I did not understand the order of your actions. I checked:MaxX wrote: 2023-07-16, 18:33 UTC TC x64 ver 10.52 or 11.0 RC1 + SumatraPDF.wlx64 1.5
4. TC hangs with no response...
1. Clicked on the pdf file F3.
2. Pressed the number '4' on the keyboard and chose another plugin to view.
3. Closed browsing by Esc.
4. Entered cm_UnloadPlugins on the command line. Nothing happened.
5. Pressed F3 again and disabled plugins through the menu.
Again nothing happened.
What did I do wrong to reproduce your error?
And what version of SumatraPDF do you have?
