<DIV><SPAN class=812524308-24032009><FONT face=Arial color=#0000ff size=2>As far
as I know, these system colours can be different depends on Windows themes, and
"anyone" can change them in Windows. So <FONT face="Times New Roman"
color=#000000 size=3>clBtnFace<FONT face=Arial color=#0000ff
size=2> </FONT></FONT>in one machine has no guarantee to be the same to
another machine. There's API to find out real colour for each system
colour, although I can't remember on top of my head.</FONT></SPAN></DIV>

Re: [DUG] Windows System Colour<BR><BR></FONT></DIV>Hi Rohit<BR><BR>I suspect
the issue is how you are replacing the pixel. I'm no expert in this but
some of the painting / drawing routines do XORs etc of the new and old colour
depending on the API and parmters set. I would check there
first.<BR><BR>Hope that is some help.<BR><BR>Cheers<BR>Rob<BR><BR>
