Media Player will no Longer Minimize to toolbar

I am using Media Player 9 to play files downloaded from Limewire. These files are saved on the Media Player as well. Since doing this, I am unable to minimize the player to toolbar mode? Anyone know why? It previously (prior to limewire downlaods) would allow me to play, pause and stop a recording using the minimized version. Now minimizing will move it to the toolbar, however, I must return it to full mode before I can play, pause or stop a song that is playing.
