Hi Leon,
How long does it need to be minimized in order for it not to work anymore ?
Are you sure you waited long enough for the disks to spinup again (if spun down) ? This can take 10 seconds or longer easily ...
Note that the way it works may make you think the disks are spinning, which especially is so when you make use of a Galery which is on the boot disk (say, C:) while the data is somewhere else (like F:). In the mean time however, the data disks spun down long ago, no matter you needed them to play (
). If you now want to do anything real with the library (better : the data) all stalls until the disks spin. With my example of the Galery on C: this does not count for the Library Tab and just browsing through there, so all seems to be alive.
