Javascript hangs in IE unless in debug mode

Question

I'm building web a javascript application using jquery, knockoutjs and less (for css).

Works fine in all browsers, except IE 9 (only tried IE 9).

It simply never starts. Nothing from the templates are shown. Unless i press F12 for debug and refresh. Then everything works fine, also works if I close the debug window and refresh. Right until next IE restart.

Answer 1

Are you using console.log anywhere? That will break in IE unless the debug tools are open.
