I will probably be putting up a few questions in the near future. In preparation for cloning my hard disk I decided to backup the primary disk, then erase and restore.
The good news is that I haven't lost anything crucial, but a few weird problems have appeared. One of these is the sizing of some pictures in my screensaver.
In the My Pictures file they have kept their original sizes, but in the screensaver program they've shrunk!
How do I fix this, please?

Well, I solved this one for myself. Kind of embarrassing, really, because the answer was right in front of my nose. I just had to adjust the settings in Control Panel to allow images to take up 100% of the screen.
I'll spare myself the humilation of asking why my internet connection is so slow - the email from Optus telling me that I'd used up my monthly allowance covered that pretty well...

Thanks for the update.

monthly allowance

Speechless.

With constant radio streams and server based gaming I could never live with that!

I've just gone on to the ADSL+ system, so my allowance was actually double what it used to be! But I've spent a lot of time on youtube lately. Mainly watching the Walker Brothers, Nik Kershaw's clip for The Riddle, and a few old Sweet songs.

How much do you get? I have 15gb per month and pay extra for whatever I use over that. They don't cut my speed though.
