TimageList problem

Hi,

In order to reduce GDI resources, I've decided to put all
speedbutton glyphs into some TImageList.
On the first image (diskette icon bmp) with clOlive
background-transparent color,
not only that color became transparent, but also everything that has
white color!!!

Is this TImageList bug or I'm doing something wrong (BCB4) ?

Is there any third-party VCL that works similar to TImageList

TIA,
