Thank you all very much for your prompt and helpful suggestions.
At the moment I do not have access to my XP comp. (getting a new psu)so am unable to Deactivate.
Pretty certain that this isn't the problem as i cannot see cursor in demo mode.
Meanwhile I'll try the text change - if I knew how to! Help please
Have not installed the patch yet. will await access to other comp. in order to deactivate.
On deactivation: my Internet Security (Kaspersky) is notifying me each time that programme is a "keylogger". Presume this is the DRM.
