how does GDI handle cursor?

Hi all,
My problem is one application set a cursor. One one adapter, it's alpha
cursor. On anonther one, it's color cursor. And it seems their data both are
wrong.
I think maybe display driver's some behavior cause GDI converting wrong data.

Some hints and Questions.

MSDN said "The LoadCursor function automatically selects the most
appropriate data for the current display device. "
Does it means when we load a bitmap as a cursor , GDI will convert bitmap
data to be multiple data (include color cursor and alpha cursor) and store
them as resource?
Where does "the most appropriate data" comes from?
What does the "current display device" means?

Thanks,
SLASH

Correct. It will create internal bitmaps.

Maybe if the cursor is displayed improperly
on 2 different adapters the problem is just with
that certian cursor.
