Mousewheel Event Bug in Version 2412 (Fixed)

Description

There have been several reports of the form / report mousewheel event no longer working starting with Access version 2412 build 18324.20092.

For more details on how users are affected, see:

MouseWheel event no longer working - Microsoft Community

MouseWheel Event stopped working properly - AccessForums.net

MouseWheel event always returning Count=0 - Microsoft Community

MS Access Version 2412 Build - VBA to override default form record - Microsoft Community

The event has two arguments that should trigger on mouse wheel scroll in suitable views of a form or report.

• Page (if page changes) - True/False

• Count (number of records scrolled) +/- integer

In the latest version, neither of these work, always returning Page = False and Count = 0.

In older versions, the Count would indicate the number of records scrolled or (if set to whole screen scrolling), the number of 'pages' scrolled.
