Windows 8, Firefox browser.
I have this bizarre problem that when I upload images from memory card using card reader and Lightroom, that I have to close the browser in order to safely remove the card reader. Lightroom ejects the card after the upload .... but then when I go to safely remove it tells me another programme is using the card, and it's always the browser I have to close. Seems weird - I asked on a photography forum but no one had experienced this.
