...ite is also true: when changing the color with the sliders, it may take sometimes until 4 seconds for the color wheel to reflect the change. That''s not a big deal, really. I guess it is only a refresh problem, which I also had on the other parts of my framework. I solved that with: def forceImmediatePageRefresh $app.repaint $app.forceRefresh $app.flush end I''m not sure this is optimal at all, but it works!
