Well, I downloaded the files to install the GNOME desktop, and also a
couple of live images. Then I spent a day with intermittent use of the
PC using Chromium as my browser, and got not a single crash. 

But OK, I will take the advice of you both, and see about installing
4.12. For reasons I've mentioned previously, I simply can't do this by
moving to Sid, so it will have to be a case of me trying to build and
install XFCE myself. Since I had a day with no crash using Chromium,
there's somewhat less impetus, I think I'll set up a virtual machine
to have a play with. 

I'll report back in a few days (again, the downloads will take me
time, everything must be done between 0200 and 0700).
