Sorry,
It's the antialiasing pref I changed from none to high. I thought i fixed the problem by deleting the pref, but then it went again to a black screen the second time I open it again.

I made a mistake today by changing the interlaced preference from none to high. How can I fix it back, knowing that each time Modul8's open, I get a black screen.
Thanks for your help.

go to your preference folder (user/Library/Preferences) and delete "com.GarageCUBE.modul8_25.plist"

We are already answer by mail, please not send messages twice.

The black screen is probably due to the option "Use full screen at startup" (menu output)
Use full screen at startup" means, start on full screen mode when you launch modul8 this is useful for especially for installations.
With one screen or if you advenced setup use your main output, if modul8 is launched without project the result is a blackscreen.
Press "control" + "t" to go back on Modul8 and change this option.
