include problem with dxutgui.h

When I include "dxutgui.h" (dx user interface classes) in my own ui class
header - call it "ui.h" - which I incude in my main application I get lots
of compilation errors in "dxutgui.h". Many types are not found and I don't
know why. The error messages start with: " syntax error : identifier
'D3DCOLOR' " (line 94).

When I implement my classes directly in ui.h there is no problem.
Can somebody help me? Thanks a lot.
