Well, that just about goes to show how good I am with computer's these days...(never had all these problems on my Amiga!!!)
For the record, I'm running Windows XP Pro. Had the foresight to create two separate user accounts at the time it was installed. I'd never noticed his user status was (default?) set to administrator...unless of course, he's reset his own account when the missus has left the computer on (AGAIN!?!).
Will downgrading the account completely remove the capability to download any file types as that user?
Gotta remember to switch the password protected screen saver on again too!
Thanks for all your help guys!!!
