No reply or post message button showing on threaded view mode

[watershed]

Hi, I have quite an odd thing: While on full threaded view (not hybrid), and in that mode only - i cannot see the reply or post message buttons.

I may have played around with my style, i've tried to put back the back up of threadbit and threadbit_search (not sure if these are actually connected) but it didn't work.

Does anybody have some clue about this?

Thanks
