Just to keep you updated I did a clean install. This did not work, as an after thought I updated Java (did not think it would do anything, i was right made no differance). The problem has been elevated.
The second time I did the installed I hunted out any refeance to Matlab on my machine even removed Data files. This weekend if I'm bored I might do a machine rebuild.

Yes that is miss spelled, but any function weather or not it is miss-spelled results in this error. MatLab appears to work normaly after this error is displayed. As you say it apears to be a fault in the spell checker, heaven known I need that working.
