yes, I meant the Text Memo tool. And in fact, the hard reset has worked! And I have reloaded exactly the same PDFs, and it works fine (at least until now).
Actiually, I am satisfied with the memos the 950 makes, i can open them in a simple text editor. However, a much welcome improvement would be a device that can export the text exactly as I have highlighted them. Do you happen to know of something like that?
Thanks a lot.
