Thanks jcl.

I will look, but actually don't expect to find anything...

Also, don't understand how it could be a Windows/server level problem given that Z12 is working fine on the same VPS (installed in a different folder).

After the successful login is the next step price download? Could a history file be damaged?

The only other thing I remember is clicking the Zorro window during Weekend when the connection box was grey - could this have hung something up?

Thanks.
