Thanks for the replies so far - but they are not the solution!

I did try creating a new user - that worked! and for the new user LyX 
worked as normal.

Under my normal user name, I found that the file ~.lyx/preferences 
existed but using the LyX interface to alter thinks made no difference.

Default Zoom seems by default to be 150%. Changing it to 100% made no 
apparent difference

Removing the preferences file and reinvoking LyX resulted in a new 
preferences file being created but again no change of behaviour.

We seem to have established that the problem is not in the LyX files but 
somewhere in the user directory.

Any further suggestions would be welcome.
