Look at the program lsof (LiStOpenFiles). lsof lists open files and
the processes that are holding them open. lsof output should help you
figure out which process/program is causing the problem. I, of course,
suspect Internet Explorer. It doesn't come from a source that I
trust. You can install Mozilla Firefox, or Opera, which is non-free,
on unstable. Both work fine in Sarge, which I'm using.
