As time goes by.... It seems *my* problems were hardware related. I don't have any issues with an external card reader, only the built-in one I used has problems. So this seems to be defective hardware. Sorry for the confusion. Please be aware that this is only related to my own postings and does not imply that others don't have further issues.
