Ditto. I started in '78. Only in the last few years have I decided that
I could see *some* justification for a GUI. Combined with a CLI, used
appropriately, one can be more efficient.

I just did that for another thread, as it happens.
The first three are checked (mount when hot-plugged, mount when
inserted, browse when inserted).

That was MHR (Mark) that that has the problem. Mine all work as
expected.

That was me that posted that. As I mentioned in another thread, that was
a leftover from another box (probably my 2.4 kernel LFS box and/or
CentOS 4.x box - I don't know if it's needed there anymore).
Last time I 'sperimented w/cdrtools, IIRC, I needed it to not have to
use the sg stuff.
Works good, not broken (yet), won't fix it! 8-)
