I notice that smys is is mis-spelling of syms and I notice that the error message has to do with spelling correction. Is it correct that the error only occurs when you enter a function name that does not exist, so the editor might be searching for a "close" name to suggest to you ?

I contacted support it was sugested, I enter these comands

>> restoredefaultpath

>> rehash toolboxcache

>> restoredefaultpath

if this did not work to do a clean install. I'm in the middle of a clean instal.

Thank you for your input.

[David Cox]

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.
