I tried to do it with my ppc and it did not work. You have to disable popups to get it to work and pie does not allow popups or have disable option.
It is very funny the site is based on moguls with downloads but not very mobile friendly.
Just curious, Why are you coming to ppcGeeks forum for a sprintmogul.net issue??
I dont know much about the other browsers but if you only have acces to that site with your mogul maybe look into other browser like opera. Goodluck
