Problem deleting audio from slideshow

[Snappypix]

Hi

I'm using the latest version of NVE and am in the middle of creating a slideshow. I've added an audio track to the slideshow, but now want to delete it from the slideshow, but don't seem to be able to.
I've gone in to edit the slideshow, clicked on the audio tab, highlighted the track, but the option to cut or delete is greyed out. I've tried replacing it with another track, but now I have two tracks on the slideshow!
This is probably a really dumb question, with an easy answer, but I can't figure it out!
I'm able to swop and change the pictures around, no problem.
This is driving me mad - can anyone help?!

Snappypix, yes I noticed this, too. I found you can delete the audio file(s) by highlighting and pressing the delete key (on your keyboard).

However, I have a similar problem where I cannot change or delete the audio file which plays in the background on the main DVD menu. The delete key (on my keyboard) does not work in this context and there are no right-click options...

Thanks St. Torg, tried it and it worked - seems obvious now, but get so used to going through menus to do everything!!
Shame it doesn't work for audio on the menu though.
