Since the update, I occasionally have a problem with my chat box in game. Sometimes I can't see what I'm typing. The chat box will open, but no letters will appear. I can still send the message just fine (it shows up in the chat log once I hit Enter). It does the same thing for whispers, though it doesn't even open up a chat box graphic for those. For whispers, it looks like just the regular screen, so to someone who knows the interface, it would appear as though I was typing a message in the inventory screen or whatever.

Sorry if I'm not explaining this very well. Let me know if you need any clarification.
