Buttons With White Text (Which Should Be Black) When Using Custom Theme

[S123456789]

Please see the attached image.  Can someone explain why this happens / where to fix it in the msstyles?  It seems that any such button that is either focused or hovered over has this.  When you actually click it, the text turns black.

In regular Windows it's Buttons, Boxes, & Controls > Buttons > Button > PushButton > TEXTCOLOR

In Firefox it's Fonts, Colors, & System Metrics > Fonts & System Metrics > HIGHLIGHTTEXT

Thanks, that fixed it.

Another issue - please see the attached screenshot.  Any ideas why paint.net is using black text for the title bar / how to change this?  The theme I'm using has white text for active title bars and greyish text for inactive title bars, but this hasn't applied to this window and both active and inactive title bars have black text.

Nope. Don't know anything about paint.net.
