Thanks for the pointers.  Sp it seems that the “interface color” setting
does not have the desired effect when themed widgets are enabled.  You
can see some screenshots here:

  http://repo.or.cz/w/git/jrn.git/commit/gitk-snapshots

The text fields, buttons, and drop-down boxes retain the traditional
grey background, while the menu bar, “SHA1 ID” label, and “Lines of
context” selector do change color.  The effect is very strange.

When themed widgets are disabled, the tk_setPalette issue described in
the comment still applies.

So I can understand better: are you saying in Windows themed widgets
are always used?
