[O] start clock doesn't refresh agenda

[Rares Pop]

Hi,

I'm using emacs 23.1.1 with org-mode 7.9.2 and when i'm starting the clock on the current item from the agenda I get the clock started but the agenda doesn't get refreshed (the yellow line on the current item is not displayed). If i hit manually refresh (g ) i get the yellow line.

Can you please help me with this issue?

Thanks,

Rares
