Forums Bug Reports channel log buffer being cleared incorrectly

I actually just came here to report this. I was running 6.2? (i can't remember the exact version) until a couple days ago. I can be off in another window, and then go back to another channel and the buffer is gone except for the last 10 or so lines of text, and the 11th is the last bit of a random portion of that line.

it's really frustrating. I'm considering finding an old version and downgrading until it's fixed because of it.

And I run both XP and Vista 32bit (dual boot) if that makes a difference (it happens itboth, and it didn't happen until I upgraded, so :))

[edit]
Okay I was running 6.17.
I just tried 6.2 and the same problem occured within less than 5 minutes. So I downgraded back to 6.17 and now the problem is gone. So, that means the problem started with 6.2.[/edit]
