Email addresses in the body of a message do not work. The link is in blue and is active, it brings up the box in which to compose a new message with the correct To: address but after about 20 seconds an error message box appears that says the "Outlook Express has encountered a problem and needs to close, sorry ...".

One then has a chance to send an automatic error report but this provides no clue to what is wrong.

This is a fault that has always been there and has been tolerated; I thought I would ask if anyone can help, please.

I should say that embedded web addresses work perfectly.
