I have owned about 5 different memory card readers used with 4\ncomputers and 6 reinstalls of XP Pro and a dozen+ memory cards. All\nof these combinations have been intermittent. That is, sometimes when\nyou put the card in the reader the pictures don't appear. I remove\nthe card and reinsert it and usually the pictures are there this\nsecond time.\n\nWhy is this? It's very annoying.
