Problem with mouse scroll wheel on cut page

Hello,
On Davinci 16.2, I used the mouse scroll wheel to scroll the timeline in the CUT page
I have upgraded today to Davinci 17.1.1, however, the mouse scroll wheel doesn't work anymore on the CUT page. Do you how can I fix it ?

Thank you

You need the Ctrl modifier now.

Thank you for your response
Have a good day
