Since the update to Calibre 9.1.0, the middle mouse button (mouse wheel) no longer has any function.
This also affects the editor, which is particularly annoying. Unfortunately, Calibre is no longer usable for me.
I have reinstalled Calibre 8.16.2 and everything is fine.

The middle mouse button (mouse wheel) is configured system-wide as a double-click-left and has otherwise worked perfectly in all other software for years. The double-click also works in the Calibre dialog windows (save file, open etc.).
Any suggestions?

My system: Windows 10 Enterprise 22H2
