It's not just you Thiago, I have the same issue and I suspect more people might have the same. For the last year basically whenever I want to type something long, I copy/ paste it on word pad of notepad, or whatever is available on the device I use at the time. So basically I finish my reply elsewhere and then copy/ paste it back to the forum to post. It's annoying but at least less annoying than having to type everything from scratch whenever it times out.
