I'm working on a theme (it's very, very early) and when I click build it says 1%, the blinking cursor moves to "extra postinst" -- is it expecting me to type something?
The progress bar is not moving one bit. Does it take a looooong time?
Did you check on the recent topic about this ?
I had the same problem and then, learnt in the forum, that you must select an icon file and not let the icon dialog box empty.
I guess I should have went into more details by saying it takes a lot of tweaking. You need to get the image I circled in red in the right position, and also make sure you sample the right spot. I can send you one of my templates for you to look at and get and idea of what part to sample and how to line it up. Its not that hard just takes trial and error.
I have the same problems and you, but I resolved, but new problems have emerged, like software, images template given wrong, I will try the former can be used
