I am unable to view my 8GB SD Extreme3 card on my Dell Latitude 4200 running PX Pro. This also applies to 3 other identical machines I have tried it on within our corporate network. Again I have tried it on our company Digital Camera which also did not let me view it. There are no GPOs in place as all other USB/removable devices are viewable. This has however been tested on an E300 and my Compaq Presario running Vista which works fine. I'v heard on some forums that XP Pro has a compatibility issue and does not let you view anything over 2GB. I find this hard to believe and a huge design flaw. I would be grateful if you could shed some light on this please.
