geegle,

Its actually a bit more complicated than that, its a leftover from 16 bit Windows where you had the size difference between a WORD parameter and a LONG parameter. In 32 bit Windows both values are DWORD (32 bit).

It appears it was kept that way to make porting code from 16 to 32 bit Windows easier.
