: I noticed that reducing the color depth to 16 bits for the bitmap,
: the problem does not occur any more.
: Anyway the missing pixel are actually "white", but I noticed
: that some of the missing pixel where in the middle area of the bitmap as
: well.
This is a fixed bug where 32-bit colors ARGB = -1 (white, with
255 alpha), and -1 was the transparent color. This is fixed
in the CVS code.

Greg
