Hi Stamatis,

I was able to create a new 35000 x 35000 RGB image in a fully updated Fiji.
It took maybe 30 seconds to create and paint it, but it didn't crash.

Fiji crashing with no error sounds like a bug in Java, probably system
specific.

My system:
OS X 10.9.3
Java 1.6.0_65 64-bit

I would suggest installing Java 7 and giving that a try, if you haven't
already [1], since Java 7 seems to have fewer crash bugs than Java 6 does,
in general.

Regards,
Curtis
