Game screen display help

For some unknow reason a hidden object game I have been playing in full screen mode will now only display in a smaller version, despite having full screen selected in the options menu. I don't know what i have done to cause this but I would like to get back to the full screen mode if somebody can help me

thanks

Did you change your screen resolution by mistake? If you've had a graphic driver update it may have done this... You can adjust this by right-clicking on the desltop and choosing 'personalise'. Then at the bottom of the page click settings. You now should see a slider which adjusts your resolution..

Thanks I did try this but it didn't work. However, I have now solved the solution by doing a system restore

thanks
