Solved Raised command buttons (2 Viewers)

Apparently, 2021 does it a different way. I'm seeing from other responses here that some folks find the setting in Database Options whereas others have a different approach. In 2021/LTSC 32-bit, IF you select a button in Form Design view, Control Formatting becomes enabled and option BEVEL gives you a set of some complex (and some simpler) buttons with raised edges. You can also choose different button shapes (other than rectangular) and can do things to blur edges or surround the button with a colored glow. But I DEFINITELY DO have the property to "Use Windows Themes" as an individual property in the button's Format Properties list. I just can't find it in 2021/LTSC even though OP found it. Microsoft and their backwards compatibility strikes again!

I wasn't offended. I meant its entirely your choice.
The handling of themes and the range of button styles was significantly improved with version 2010.
