Hi, Once in a while my book port will get into some mode that doesn't let me press any keys, but at the same time it isn't the lock mode because there are no lock beeps. So I try to take the compact flash card out: Memory card removed. I put it back in: Book Port 2.3.0.0 ready. In other words, it totally locks itself out. Then when I try pressing other keys, it starts making the error beep tone, as in the double-note one. So when I finally hit reset, it comes back to the book port ready thing, but with the same voice settings, and it doesn't lose anything except the clock. Does ayone know why this is happening? Thanks, Simon
