I'm trying to use Multi-order Shipping for the first time. I'm on a mac and have tried both Safari 4 and Firefox 2, but am having the same issue with both. I cannot get my choices from the drop down menus to "stick". For example, I'm trying to choose Priority Mail as my shipping method. I can click on the choice, but after I do the menu goes back to the default "-Add Service Type and Package-". Can't even click on the "-Add Weight-" drop down because it's grayed out.
Help please?
