MouseWheel event no longer working

Anonymous

In MS 365 Version 2412 (Build 18324.20092 Click-to-Run), in Access Forms, the MouseWheel event has changed. In the event handler: Private Sub Form_MouseWheel(ByVal Page As Boolean, ByVal Count As Long), the 'Count' value is now always zero.

Until this update, the Count value has always been -1 (scroll up) or +1 (scroll down).

I have several forms that rely on this event that are no longer working.

I have rolled back to an earlier update to correct the issue, but this is not a sustainable long-term solution.

Was this a deliberate change? Or will it be corrected in the next update?

    The fix is now available in the Current Channel version 2501 (build 18429.20132) released on Thursday 30 January.

    It was also fixed in Current Channel (Preview) version 2501 (Build 18429.20114) released on Friday 24 January.

    However, the fix is not yet available in the Beta Channel.

    I have just updated my article on the AccessForeverblog site

    Exactly same problem with Access 2019 : Count is always 0

    This BUG is independent from any specific database: it appears in all databases !

    Can you provide a copy of the accdb in question, illustrating this behavior?

    We can't upload files here, but if you can put a copy in OneDrive or DropBox, etc. and provide a link, it would be helpful in replicating the behavior for analysis.

    Thank you.
