Hi, I've got it to work by shrinking the height of the button area by half, so that the entire button area has features. So I'm guessing my problem was caused by part of the button region has no feature?
Anyway, thanks a lot! Perhaps this should be in the best practices section in the dev guide? :)

Take a look at the Virtual Buttons section of the Dev Guide, there's a list of best practices.

I can't really tell what's going on from your screenshot, could you possible send the full target image and config.xml file to

?

Hi, I can see the virtual button boundaries rendered correctly on my screen.
It seems I only have features in part of the button area, is this the reason?

Could you attach your config.xml file so we can take a look? You can use the VirtualButtons sample code to render a rectangle around your buttons, to make sure the boundaries of each button is defined correctly.

Also make sure your target has features in the button area, take a look at the feedback from the TMS system.
