Problem with character scaling [SOLVED]

[Venus]

I'm making a little interactable cartoon as a Xmas gift for a friend of mine. The resolution of my game is 640x480 at 16-bit color. My main character is 270x463 as it is a close-up shot of him and you can only see his head and torso.
When I start the game, his sprite is scaled up incredibly. I've checked the sprite properties and there it says: "This sprite is drawn for 320x200 and will be scaled up or down for other resolutions." I see that this is the reason why it is scaled up. My question now is: Is there any possibility to change the sprite's properties, so that it isn't scaled up anymore? I don't want to resize the image in my paint program to a smaller size, coz I don't wanna loose the detail in it.

Thanks in advance

When importing the sprite tick the "Import sprite for 640x400 resolution" (or something like that, I haven't needed it in ages so I don't remember excacty what it says) checkbox.

Argh, it's so simple. Sorry for being stupid. Thanks a lot Ishmael. Works fine now,
