Screen does not rotate

[Rob.Skully]

All of a sudden my screen does not rotate anymore.
I went onto settings to make sure the auto lock switch is not checked.
What else can I do ?
Thanks

Tried a complete cold re-boot? Other than that all I can think of is a system restore.

I switched the setting on & off and now it works.
Thanks for your reply.
BTW .... what's a cold reboot ?

You should try checking the auto-lock option, then flick the volume button and see if that helps.
If that doesn't help, then try a hard reset.
Otherwise, if you have the time, restore.

EDIT - ninja'd.
BTW, it's also known as a hard reset. It's when you hold the Power and Home button for 10 seconds and it reboots.
