Reaper 6 theme Toolbar button outlines are gone. Theme Tweak fix?

[Thonex]

Hi Gang,

In Reaper 6, my toolbar buttons outlines are gone. They look like this -- not unlivable, but not clear either:



Is there a way in Theme Tweak to get the outlines to look like they used to in my Paulie theme in V5?



Thanks for any help.

Cheers,

Andrew K
