Sorry for the very late 'thank you' people but I have been away from my computer for some time. I realised after posting that it was simply a question of the same colour being shown for both bits of the net. I simply printed out the same pages twice on different coloured paper! Anyway, thanks Robert...

Would like to attempt this model but the net for the outer layer seems to be missing. Can anyone help? Thanks.

Thanks for all that stuff, Robert. I obviously just need more practice and, I guess, some extensive manual reading! Just loaded Great Stella on my wife's desktop (networked with mine) and Stella behaves fine. Her desktop also has a dual monitor configuration so the puzzle continues. Thanks again for...

Hi Robert, it is looking like I have more problems than the simple screen redraw workaround. I thought I would have a look at making the final stellation of the icosahedron and checked your notes on it. I then tried to measure the dodecahedral edge of the net using measurement mode. I seemed to sele...

Yes, I remembered to do the specific change but thanks anyway.

Hi Robert, a bit of disappointing news. Whilst there has been a great improvement in the stability of the Stella windows, the problem does still occur. I have noticed it since upgrading to Great Stella. It is interesting to note that, if I have been looking at a print preview, then this is the view ...

Thanks for that link, Robert, it set me on the right track. I had a feeling it was something to do with the NVidia graphics card and my having multiple display units. After a bit of searching around in the NVidia setup area I discovered that it was possible to change settings for individual programs...

Hi Robert. I have been experimenting with the problem and have the following observations:- After starting the program and leaving the default icosahedron and its net on the screen the windows turn white after a minute or two. 'Undo' will bring the images back again (albeit with an error message as ...

Sorry - should have mentioned that the white areas seem to appear quite randomly - I am not performing any keypresses or mouse clicks when it occurs.

Hi Robert, thanks for your prompt reply. I suspected it would be a problem and not a feature! My computer is a desktop, home-built and now a few years old (4?). I am running Windows 7 Home Premium. The processor is a Intel i5-3570 CPU @ 3.40 GHz. I have 8gb of memory installed and the graphics card ...

Hi, I am a Stella newbie so please forgive me if this question is easy! I notice that the two side by side windows containing the polyhedron and its net seem to randomly blank out to white. Also, when looking at a print preview of the net, the main screen returns leaving the print preview in the two...
