Where is "Set Button Picture" button?

[ichigo]

I'm trying to follow the instructions on p. 99 of Toast.pdf, headed "To edit the TV menu button text or graphic for a video:"

 

I have Selected a video, and clicked Edit.

I don't see either a Text tab or a Video tab (but the manual says "Some files may not have a video tab") so (as instructed) I click the existing button graphic. It brings up my movie in Toast Video Player. I select a frame from it.

 

Now the mystery:

 

The instructions say "Click Set Button Picture" BUT I can't find any place to do that.

 

Where is it lurking? What else am I doing wrong?

Do this instead. In the Video window where you see the list of the videos you added and each one has a thumbnail image, click on the thumbnail itself. A scroll bar appears beneath the thumbnail. Drag it to select a different part of the video for the menu button image.
