Hi Hernan, I am not able to import the fuel error. I get the following: Maybe you can share the image? How can I reproduce your error?

When trying to open a grapher, I get a yellow-cross red morph window inside #setPaint: . The transparent color passed as argument came from AthensCairoSurface>>clear The same figure used to open without problems some months ago. All the Roassal examples open without problems. That's why here is the link to the fuel out stack with the halt previous to the crash : https://dl.dropboxusercontent.com/u/103833630/Debugger-Stack- AthensCairoCanvas-2017-02-15-192251.zip Is this a well-known bug? Any suggestion?

Hi Hernán, I am not able to reproduce your problem since I cannot open your image (I use OSX), and apparently there is a problem with the font. I cannot open a code browser. However, I suspect that the problem is that a nil value is used as a color. Check this: v := RTView new. shape := RTBox new color: nil. v add: shape element. v Executing this code seems to produce the same error. Maybe you want to add a check on your side?

I am debugging the TRMorph>>drawOn: method and there is no way I can figure out which one of my Grapher objects should I change its color.
