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
