strange chat window behaviour

Hi.
My chat window shows less and less lines of text the longer I stay in the game. For example, lets say the height of the chat window (by chat window, i mean the window that displays when you press "~") is such that it can display 8 lines of text. After about 15 minutes, it will display 7 lines of text. The chat window stays the same size (height and width), but it displays less text because the lowest line in the chat window, keeps on moving up. So the first line i see moves further and further away from the tabs (all, guild, team, etc). How can I solve this problem?

Figure I couldn't find the answer and I have the same issue, so I'll bring this thread back to life because I have the same problem...

Ya, this happens to me. Not sure what triggers it. I will have the chat box sized to show like...12-15 lines of text...but at some point the lower part is filled with "blank" lines.

The text is there above this blank area. There shouldn't be a blank are beneath the active chat text...

This has happened since te Nightfall release...best I can say.

I've also noticed that it's fine if I un-check the 'trade' option....It's as if the trade channel is building up extra blanks at the bottom or something...
