Does anyone know why when I transfer a screensaver to my phone, it only takes up the middle area of the screen?

My resolution is 240x320, and I am using a screensaver that is this size. Am I doing something wrong?

How do I get it to fill the whole screen?

What phone have you got? Which screensaver are you using? Are you using it as a screensaver or an animated wallpaper?

I'm using a nokia 6500slide, and as far as I know, I'm trying to use it as a screensaver.

Humm that eliminates my theory. Have you tried other 240*320 screensavers to see if they work?
