I use flash drives every day. When done I close the drive and click the eject icon.
Normally Windows then removes it from Explorer file display.
However, if before I try to software eject, I had opened a .JPG file on the flash drive, then try to eject, I get this message:
In order to clear this I always have to restart, which then correctly gives an all clear software eject. When I had NOT opened a .JPG file but only normal files the eject works fine.
In the April updates there was some kind of fix for pictures. I think this fix or the original problem is the cause of this current problem as this has never happened before.
