This casual game might be fun but my screen is only 16 inches and I can't use the buttons needed to play the game. I also tried to change the size of the game to adjust it to my screen. Is there anything I can do? Resolution, maybe? I am a little frightened to make changes for fear of damaging my computer. Do I need to buy a larger monitor. Thanks for your advice.

Does the game have an option to play Windowed as opposed to full screen? Most casual games do.

I haven't been able to see "windowed" I click on the button that says "full screen" but it will not change to anything else. I don't know what else to do. To get out of the game I had to shut down my computer. When I did that I was afraid to re-install the game. Guess it is a loss.

If you click Options on the Main Menu of the game, you should see the option for Windowed at the bottom.

What resolution are you using?
The game uses 1024x768. Most monitors have higher resolutions than that, but if you have your monitor set to a lower resolution, you won't be able to play Windowed. So make sure your monitor is set to 1024x768 or higher.

Pbx is I can't click options. It doesn't show at the bottom of the screen. Only the button with a check mark which doesn't change when I click on it. I am using 1366x768. I hope I don't run into this pbx with another game.

On the main menu you should see

Options is not at the bottom of the screen.

When you click Options,
you should see a box appear in the middle of the screen. Although Windowed is the last thing listed, it's nowhere near the bottom of the screen.
It looks like this

When the circle next to Windowed is filled in (by clicking it with your mouse) the game should change to Windowed.
