Sometimes, for no discernible reason, text entered into the chat textbox is in italics. I'm sure this behavior has to be programmed in somehow, but why is it doing this? What is it trying to indicate?
I've occasionally noticed this too - what is typed appears in italics while typing, but upon hitting ENTER the text appear in chat in normal font.
I see this also quite regularly, the same symptoms Scarponi lists. The chat input control font type gets changed for some reason. I'd imagine it might not be too hard to see what's accessing and reformatting the control in code (unless there's some self-defeatingly clever pointer thing going on).
Ancient bug, super low priority... hehe http://forums.cardhunter.com/threads/italics-in-mp-lobby.818/
Seeing as the game writes the "Type your message here" prompt text into the chat input control in italics (when the input is empty and out of focus) I'd imagine the formatting gets confused with some sequence of sending chats and doing other stuff with the lobby UI, some unhandled/unconsidered state transition. Maybe some non-italics enforcement on any first incoming input character would be a simple way of fixing it without needing to go through all combinations of UI interactions? Just throwing ideas out mostly to maybe prompt a new idea for someone who unlike me actually knows what they are doing and can do something about it (should it ever be deemed worthy of actually doing something about).
