Hi,
I always had
Go DRIVEBUTTONS=multifunc,hideempty
and when I put a SD card into my card reader the card reader drive letters will be shown.
With the latest beta (just using 10.5.0.3 (4808)) this does not happen anymore,
although the drive is in the "Savely Remove Hardware and Eject Media" list and selectable via explorer.
I've changed it to
Go DRIVEBUTTONS=multifunc
and now all drive letters of my card readers are shown.
It looks like a bug in the latest betas or also release?
Maybe it's also possible to only show the drive letters of the card reader which are really in use?
