Shot in the dark: try booting in Safe Mode and see if the freezing still occurs. That will purge the font caches at the same time. Last time I had such problems, it was down to fonts.
The problem isn't nasty enough to induce me to live in safe mode for more than a minute or two, but I'll try the safe boot to purge those caches.
Thanks for the suggestion.
