* I'm not sure what the second parameter is (the datatype is likely wrong), other then this:
* Under XP if I pass
* char b[] = "";
* the theme is applied with the screen redrawing really badly (flickers)
* char b[] = "\0"; where \0 can be one or more of any character, makes no difference
* the theme is applied smoothly (screen does not flicker)
* char *b = "\0" or NULL; where \0 can be zero or more of any character, makes no difference
* the function fails returning invalid parameter... very strange
