According to
***this page*** at HerInteractive,
Games from #16 The White Wolf of Icicle Creek through #24 The Captive Curse have three display options:
- Windowed
- Fullscreen 1
- Fullscreen 2
That would include the Triple Dare games.
That webpage also says:
To adjust the display setting at any point during gameplay, click on the "Cog" icon on your taskbar to open the Options menu, then check the display setting you prefer. Changing your display setting will not interrupt gameplay and can be done at any time.
Have you tried changing those "Cog" settings to see if any of them gets you a larger image?
