Thanks to both of you for answering my question. I was having one of those incommunicado days yesterday and the frustration was tremendous. At least I know now that I'm not the only person has this problem (though I'm very sorry to hear that you have to deal with it as well.)

I adore writing and written word is my primary means of communicating, and having these episodes where I can't form proper sentences and can't bring to mind even simple words is a nightmare. -_-
