Searching through the forums, this seems to be an issue with Fusion for quite some time. There seems to be no way to change the background color of a button. It amazes me that this is not possible given that other systems (e.g. Visual Studio) allows such. Another development system I'm using, Neobook, has this feature. It's as simple as selecting the color as one would select colors in Fusion.
For the regular Button object, one cannot uncheck the System Colors option. Using the Bouton CS object, I can uncheck the System Colors option and then change the text and background color of the button. However, this seems to have absolutely zero effect on the actual button. The button background seems to blend in with whatever the color of the object/space the button is over. The text is not visible at all. If I enable the System Colors back in the Bouton CS object, the button background still blends in with whatever it's on top of. Text still not visible. Is this a bug in the Bouton CS object?
The project I'm working on is as a Windows application. I'm using Fusion 2.5 Developer through Steam (i.e. the Fusion 2.5 Dev released through Steam).
