I don't know whether there's a sensible answer to this beyond getting a more up to date browser (am using Mozilla 1.0.1) which would be unfortunate as I'm not in a workplace that allows that, but I've been having an intermittent problem, most often with long-ish threads, where beyond a specific point on a page, and on all subsequent pages, there will be some garbling of post titles, quote and modify buttons and so on when I mouse over them, and when I attempt to reply, all the buttons above the text window are garbled and some or all of the text in the text window, both mine and the post to which I am replying, will be invisible.
I mention this now because I have an example; it appears to be consistently happening with page 4 of the "Reasoning behind political views" thread in the Touchy Topic forum, from the top, and also affecting page 5 of that thread.
It doesn't happen very often and I can come back to threads from home eventually anyway, so I'm not asking for this to be a high priority, but I thought it was worth mentioning.
