As mentioned before, I have an issue with the rendering of my navigation bar button:

It is a Visual C++ MFC application (MDI) and Microsoft Visual Style is "Office 2007 (Black Style)".
The Windows Blinds theme is "Ice".
If I use "Lantana" the text is visible:

So maybe it is a skinning issue with "Ice" itself. But white text on yellow background is never a good idea.
