Sprites not appearing on Play?

[wyvernfist]

I placed a sprite object through plugins, saved & compiled. The sprite shows up on the Level Editor. When I hit Play, the sprites are nowhere to be seen?

To clarify, this is on a custom map, not the Sample.

The same sprite does appear on the Sample map with no changes.

I did more messing around; it seems the sprite disappears after being used as a condition in an event.

Removing the events makes the sprite appear during Play.. I will keep messing with this.

I confirmed the sprite was visible, then created an event to make the message box appear (with nothing in the event relating to the sprite) and the sprite was gone when I hit Play.

[wyvernfist]

The event (ShowMsgBox when space bar hit) isn't functioning.

This was on a Win7 computer, and now confirmed on a Vista computer.
