Help,Treeview and ToolButton can not show Image on some video card

I build a application with Treeview and ToolButton on WINNT 4.0.on some
PC it works not correct: the Image in treeview and image in ToolButton
cannot show out.
    1.if a win98 system with a Nvidia 128 Video Card. But on win95/NT
with Nvidia 128 card it show out.
    2.if a win95 system with ATI rage video card(this is a IBM PC).
    3.if a win95 system with MGA G100 video card(I test it on many HP pc

with this card).
How can I resolve it?Does this is a borland bug?
