Hi - thanks for the suggestions.  I couldn't get the Grub screen to come up (Using VMware Player 6.0.2) so in the end I edited /etc/default/grub and commented out the line GRUB_HIDDEN_TIMEOUT=0 (by adding a # at the start of the line).  Then ran sudo update-grub. This caused the grub menu to appear on startup, and selecting 3.2.0.63 did the trick.

I hope they (is that VMware or Ubuntu?) come out with a proper fix in due course.
