Is there a way to change the color of the message background when it appears.
Example for a warning message when it displays, perhaps the color red for the background.

If you have a BW interface -> then, right click on desktop -> Properties -> Appearance -> Choose the Scheme/item to change and select the color.

I would like to do something with BaaN. Is it possible?

I don't know about IVc4, but in V you could use the UI graphical objects to build your own message dialog and achieve exactly this kind of effect - you could even have purple spots on a red background. :rolleyes:

But are you really sure you want to do this?
