XY graph has 'negative colors' when used on PC with XP

[Richard Nicholson]

I built an application with windows 2000. I have distributed it. One customer using XP has found that when the XY graph begins to plot the background and gridline colors swap from black to white and visa versa. We have tried our program on an XP machine here, and can not replicate the problem

This sounds like an issue with the graphics driver on that XP machine. I've seen all kind of weird issues due to driver bugs.
Is this an older video card? See if there is a new driver available for XP. They might also want to try other display settings e.g. 32bit color, 24bit color, 16bit color.

Also try to temporarily reduce the graphics acceleration (display control panel..settings..advanced..troubleshooting) by a click or two. Any improvement?

Thanks Altenbach, the client found this.

There are 3 choices available in Windows XP, control panel, display properties, appearance, color scheme : silver, default blue or olive green. It seems that olive green and default blue gives the normal graph background .... and silver (which I had selected) gives you a black graph background.
