GDI+, Backbuffer and _GDIPlus_MatrixTranslate how to center letter?

[Morrison]

Hello,

after a while I finaly managed to get the letters in the middle of the Windows, but now I´ve got the letters twice!! How do I get the letters only once???

Maybe the _GDIPlus_MatrixTranslate is the wrong solution, does anyone have another??
