I'm an old FileMaker user (in both senses) but my experience is almost entirely macOS. I've just gotten a nice Windows laptop (a Dell XPS 15 touch) and am trying to do some FileMaker 16 work on it. But the icons in the Inspector are so tiny they're unreadable. If I wasn't already so familiar with the Inspector on the Mac, I don't think I'd be able to use the Inspector in Windows.
I've found the Windows configuration options at Windows > Settings > System > Display > Advanced Display Options... and I've enlarged text a little, which helps some things. But my problem is less with text and more with the little icons in the Inspector, for example, the icons on the Inspector's first panel that you use to resize objects or align objects.
Can somebody throw me a clue on how to fix this?
