Hello everyone, by trying I found a solution for me (during my wedding, hehehe). When my chatwindow do not take any letters, I do now the following: with the palms of my hand I press simultaneously so much keys of my keyboard, I can. Within the num-block. That seems to release a key combination, no idea about it. After some tryings letters are suddenly jumping up in the chat-window again. And it works for a while again. I have not to logout. That is wonderful. Logging out can ruin the prettiest moments. It was nearly, to ruin my wedding. I hope, it works for us all, who have to struggle with this little bug. All the best for you. Have fun.
