Problem solved!
ThrashZone you had the right idea!
After uninstalling IE10 and getting back to IE8 I updated to IE9. This still showed the text I didn't want in the Command Bar but in IE9 (and in IE8 I suspect but didn't try) you can right click on a Command Bar icon and then get an extended Customise dialogue which allows choice of all icons, all text, or a mix. I selected 'all icons' and the three missing ones returned (!!) and survived a further update to IE10, where strangely the extended Customise dialogue does not exist.
So I'm now very happy and most grateful for the support.
