I'm using the 7.5.6p2, which I think is the latest. One of my members reports that he has given up posting on my forum because when he types in the edit box, the text being put in the box doesn't keep up with his typing. Characters get missed and don't get put in the text box. Also, when he gets to the bottom of the edit window in a post or reply, the text goes below the bottom edge and he can't see what he't typing.
He is on a PC running Vista and is using high speed cable for his ISP. I don't think this is a Threads bug, but I'm hoping someone here has seen a similar problem and may know what could be causing his problem.
