[FLASH-USERS] problems with refinement in FLASH3.1

[Seyit Hocuk]

Tomek, it was not like this in Flash2.5. You can even see this if you 
use different refinement levels with the Jeans setup making 
perturbations slightly stronger. It is easily reproducible. I think 
guard cells get their information from parents and we know that they are 
not evolved in Flash.
