Hi there,
I can confirm the problem
Excel 2010 worked fine until Fall Creators update of Windows 10
(or maybe a bit later)
Microsoft updated Windows 10 and also improved Scrolling of touch pad devices
(in my case it's a Synaptics Touchpad 64bit Enhancements).
Scrolling is smoother in Windows Explorer and other ares
BUT - Excel 2010 is completely not working with vertical scrolling (Table and any other dialog).
Seems that Excel intercepts the messages not according the updated drivers.
(even Save Dialog, etc)
Hope there will be an update for Excel 2010 (64bit) soon so we can all use touchpad scrolling again.
