when having the chat history enabled very long messages will overlay over the textbox (T).

here a nice picture:

what does this mean? im sorry i dont get it?

that means that when you have very long messages in the chat history, these old messages will go over the chatbox (T) and make it hard to read the text you type.

just see the picture and you'll see how the last message in the chat history (H) is displayed over the chatbox.

Not really sure it's a bug but looks like it could be a pain

ooooo yea looks annoying!!

well u can close the history to write and open it afterwards again?
never had a problem with it, and i dont think its really a bug
