colors issue in VNC 4 viewer

[Satish]

Hi all, 

I have a custom application implementing the basic VNC server protocol
( RFB protocol version 3.3) that sends out pictures to the RealVNC
viewer on a Windows 2000 PC.

The application works fine when I use the older 3.3.7 VNC viewer
application on the PC, but if I use VNC 4.0 viewer on the PC , the
colors on the images are off.  ( the images themselves get displayed
OK, its just the colors that are not accurate)

I'm using the viewer in "read-only" mode, and my server application
sends out raw-encoded pictures in 32-bit color.  I clicked on the
appropriate check-boxes on the PC viewer to support raw-encoding and
32-bit color.

I'm using VNC 4.0 viewer on the PC since I found its much faster than
the older version ( thanks to James Weatherall for the tip ! ).

Is there anything I can look at to explain or fix the color problem
I'm seeing ? Any suggestions or advice much appreciated.

Thanks, 

Satish
