O$816 - Win10 - Ever seen windows styles suddenly start to try and use Mac Styles in dev?

[Phil (OmnisList)]

Hi there,

A number of times, I've been doing some things in O$816, and suddenly 
the fonts all change, most obviously on a headed list, using the 
notation inspector, I can see that for some reason the styles have 
decided that my windows machine is in fact a Mac?

The only resolution is to quit Omnis and restart...

Is this just me, or has anyone else seen this?

This is a desktop application.
I half think it might be when I check out something out from a VCS, but 
I'm not 100% sure of that...

I need a bit of clarity before reporting it to Omnis.
So, anyone else seen this behaviour?

Thanks.
