I found a UI bug in Windows with DARK Theme. Look at the attached file...
As you can see since I'm using DARK Theme for my Windows, I cant see those Texts! because they uses custom and wrong colors instead of Windows native colors
So Windows theme cannot overrides them
Thanks.
Generally, Fiddler does not use Windows theme colors because it needs more different colors than Windows can provide. See https://groups.google.com/forum/#!searchin/httpfiddler/theme$20color%7Csort:date/httpfiddler/BgNl_j_IPoc/9RnD6Ka7BgAJ for some mechanisms to manually configure colors.
