Another 2.5: particle visual vs render

Hi all,
I’m trying out 2.5 and I’m really enthusiastic about it. Bu I’ve noticed a little issue: I ‘m trying to improve my recent 2.49 characters, pretty furry ones I should say, and I’ve encountered something I didn’t expect. When I hit render, no particles showed up! Later I figured out it’s caused by turning off the particles’ visibility in the viewports. Is that intentional, or just a bug?
