Emmanuel,

Unfortunately there seems to be a little bug in the new beta 11.
When I try to render the attached file, it gives the rotating cursor, then the red/green squares, then nothing.
When I load the same design in v3.0 there's no problem, and after waiting a bit there's an image.
Compressed the file is just 1.8 Mb, uncompressed closer to 5 Mb. Maybe it's a regression bug?
