Builder does not work if many icons are selected

[HStokbro]

I tried selecting 50 and more icons on the builder site. I need a lot of icons:
http://andymatthews.net/code/jQuery-Mobile-Icon-Pack/builder/

The download buttons just reloads the page, when a lot of icons are selected

Here is a codesnippet for selecting 50 in the console:
$('i').each(function(i){ if (i<50) {$(this).click()} });

(I am using newest Chrome on windows)
