Noticed a peculiarity with reading.DOC files – I updated a file having added a couple or paragraphs on the end of the document and although I can read the appended material on other devices, the 511 is still showing the old version of the file. I’ve had a similar experience with my PDA, and the workaround for that was refreshing the device by inserting the SD card while the device was switched on. I’ve tried the same trick with the 511, but it doesn’t seem to help.
