Yeah, that is consistent with my experience on Windows. I found that if I scroll up far enough to get the relevant part of the conversation onto the screen, the Jump to link works again; it’s seemingly only when it’s not fully loaded into memory that it does nothing? I’m just making an educated guess, I could be wrong.
@RitaB Thanks for sharing your findings. Just tried what you reported but here I was not able to make the “Jump to” link work whatever I tried. Same on all computers.
Would really be helpful if others report if they experience similar things, to find out if it is a general problem or related to specific environment.
