Have you tried the Q/E key?
My mouse stopped rotating also and it checks out fine on other programs.
For me it started maybe a week or so ago. I reported with F8 an experimental build
I checked the mouse settings in the options menu, and indeed that is where the proplem was. I have not reassigned the mouse wheel to rotate the pieces. Thank you Alex
And thank you also eastofdeath for your suggestion too.
This is not-quite a bug, controls were just re-set to a new default due to a new system being put in place. You can change this back by re-binding your wheel up/down in the new Control settings.

Try to check mouse settings for games in Windows settings tab (assign functions for weel - as a mid button)
