Desktop - Athlon 2X4 640 processor 16GB RAM 3Ghz, Windows 7 64bit.
It works normally if a card is not inserted, I have tried two different (SD) cards btw and it behaves the same with both. Yes, both cards work normally in the device (digital camera).
Usually when I insert any card, autoplay kicks in and it offers me the option of opening folder to view files.
*Sigh* - right, just as suddenly as it stopped working, it has now started working again.
Must be my impatience Methyl - then again, it's normally ok - patient or otherwise.
