MapleStory chat problem

Every since the last patch I'm having trouble with all sorts of chats. Sometimes it shows up for me but others can't see it and other times it just doesn't go through. I can change channels, etc. fine and all that so it isn't a hellban if those are still around. Anyone else run into this problem?

Yea I get this sometimes when I haven't restarted my computer for a few months. Just restart computer (not just maple) and it goes away.
