PRS-900 Slow when lots of notes...

[vxf]

I use my PRS-900 a lot - and one of the things I do is reading PDFs and taking notes on them.

In a couple of weeks I have read about 60 pdf files and ended up with about 6-700 notes on them. I want to have the files with me, so I have been storing them on an SD card in my reader after I finish reading them. So at any given time I will have 10-20 PDFs in the PRS and the other 60 on an 16gb SD card, in the PRS.

Now, when I open a file (not a file from the SD card, any file) and write a note, things slow down. A LOT. For example, if I scribble on a page, then press the page-turn button, it takes anywhere between 40 and 50 seconds to turn a page. And it has been getting progressively slower as the number of notes increases. To the point of not being usable.

I think it has something to do with the way notes are being stored. For example, if I return to that page (which already has notes) and then try to turn a page, it will be the usual one-second page turn. But if I add any notes and then try to turn the page, it will take almost a minute. Even deleting a note does it. It's like any modification to the notes, slows it down.

Also, if I close the create/edit tool before turning page, it does not take nearly as long to turn a page. But closing the tool takes also about a full minute, if I have added any notes.

Of course, if I take the SD card out and the number of notes goes back to <200, then I don't see any delays.

Anyone else have this problem? I keep taking the SD card in and out as I need to, but it's getting annoying. It would be nice if I could just turn it off, but if it is in, my reader wants to add the notes to the main list of notes, and it becomes unusable.
