Form not scrolling (1 Viewer)

I have a form that always used to mousewheeel scroll and now it doesn't. I can drag the scroll bar but the mousewheel won't scroll. I even checked FrontEnd versions from last year to make sure it wasn't just a corrupt form. I am using Office 365 Click-To-Run Version 1707 Build 8326.2073
Can someone tell me if they recently updated something that would cause this issue? I have the form view set to continuous forms. I will add that I have other forms that have subforms and those scroll just fine.

Thanks
