Saving axes graduation (Graphics 2 window)

Some months ago I opened a topic about which, if a GeoGebra activity is saved such that the dimensions of the axes of the graphics window depend on the value of a variable, then when the file was reopened we could observe that those dimensions not saved correctly but with a fixed numerical ranking.

This has already been corrected immediately.

Now I am working with GeoGebra 4.0.20.0 Webstart, Windows XP, Java 1.6.0_26

I think that with the version 4.0.20.0 (and I also think that at least since the 4.0.17.0) something fails again when we keep the axes graduation/dimensions.

I will explain:

If I work with the graduation of Graphics 2 window defined by some variables and I save or export the file with the Graphics 2 window opened ... everything works fine.

But...

If I work with the graduation of Graphics 2 window defined by some variables and I save or export the file with the Graphics 2 window closed, then when I reopen the file, the graduation of Graphics 2 window is not saved correctly but with a fixed numerical dimensions (perhaps the default graduation)

And this fact can be interesting: supposse that I want do an activity with students who initially show only the Graphics window. At certain momnet of the work I want to open the second window for more information, presented in a certain way. This is not possible: The information is not presented as I had saved!
