Bug Alert: MouseWheel Event Broken in Access Version 2412
A critical bug in Microsoft Access version 2412 has rendered the mousewheel event non-functional, impacting form and report navigation.
Bug Description
The bug specifically affects the Form's MouseWheel event's two key arguments - Page and Count - which are meant to trigger when users scroll through forms or reports.
In version 2412 build 18324.20092 and subsequent builds, these arguments consistently return False for Page and 0 for Count, effectively breaking the mousewheel scrolling functionality that many Access applications rely on.
Current Workaround
The only known workaround as of today (2025-01-17) is to roll back to version 2411.
