Guild Wars 2

So, every now and then when I am typing a message, it gets deleted and replaced with a message i had typed before. How do I fix this? It has been occuring since yesterday, and I have tried re logging but it doesn’t work. It is starting to get annoying having to re write the new message again, and deleting the old message.

are you Accidentally hitting the up arrow… as i know that shows yr old messages..
