When using the "Rough Draft" folder of Yahoo Mail to complete part of the text to be sent, centering marks (3 columns of 3 cubes) appear over the text when typing. These marks move syncronyzed, showing always the beginning, middle and the end of the text typed. When touching some keys, the marks desappear but the typing is blocked. Otherwise, when touching some keys, the typing unblocks but the marks re-appear. This only happens when using Firefox. It does not happen with Internet Explorer or Chrome. But I like to work with Firefox. Excuse my poor English. Best regards.
