The Legand of Zelda: Phantom Hourglass... Problem!

For those of you playing it, I reach the section where you are supposed to close your DS and re open it. so that the third crest will appear. The problem is, I'm playing on an Emulator (NO$GBA 2.6a). :)
How do I continue from here?Thanks in advance, Dor.

Minimize the emulator and bring it back up a moment later, that works if I remember correctly.

Wow! Thanks :D It worked.
Thanks a lot :P
