Roberto, The first thing I checked was the layout. Nothing changed. And I don't think is related to shortcut keys, because clicking in a different tab, and the problem goes away for that tab.
It's a very weird scenario. I started writing this e-mail with the problem in the current window and when I got in the third line it went back to normal, and now it just happened again. Another point is that I can type a word with 100 characters, if I type a space or a comma for example, the word persists. If I press a control key (like ESC, or PrintScreen) or click out of the text field the word disappear if I never had written it. I can switch my layout between Portuguese (Brazil) and English (US) but the problem persist independently. Anyway I don't have any shortcut key configuration for changing layout. Thanks for the help. I look forward to hear from you. Regards. Paulo On Thu, Dec 7, 2017 at 5:12 PM, Roberto C.
