resizing main chat window to minimal = crash

[SnappHF]

I have searched for similar posts to see if someone allready posted this. but I couldn't find any. So I am sorry if this is allready posted.

I stumbled into this the other day while in Plane of Hate. I wanted to reorganize my windows and minimized the main chat window. Doing that I crashed emediately.
I have redone the same procedure twice after and crashed doing the same thing.
And it doesn't matter what zone you are in.
