Comment 77 for bug 346912

I've been having exactly the same issues as many of the above posters have had. I'm hoping to have a go at the Milan solution a bit later (deleting a few hidden files). One other piece of info though.
A piece of extra info not necessarily mentioned above:
there is no problem until I put a removable memory device in (it's happened both with an SD card and a usb memory-stick), within about a minute of the insertion of such a device the pop up with the choices that won't go away is on screen, and if I choose re-index I can't use my machine because it spends a long time greyed-out.
