Thanks for the speedy replies, Mithrascruor and Exvor. More success using the / instead of the * I had used before. I don't know what's wrong but it goes through the windows directories twice, then after a couple of grep /proc entries, which return Invalid Argument, it stops. (I copied the windows partitions over to this box for the data, though I don't run it on this box). I don't know if this is peculiar to my distro Suse 9.1; I tried it on my laptop, which has a Debian based distro (Libranet 2.8.1) which would not run with the -D switch. It did find my .bashrc file in my home directory (I think SuSE makes it more difficult by using etc/profile referring to /etc/profile.local or some complex set-up) but then it stops after two "no such file or directory" entries in a /~/.kde directory.
Perhaps it is running out of memory (500Mb on the desktop and 384 on the laptop)? I would have thought it would crash more readily with a GUI, but maybe SuSE has built in a work-around for this?
