I'm using shipping my Ubercart shop together with Paypal Payment Standard.
I've enabled the shipping module, in order to calculate the shipping costs.
It takes a bit to calculate these costs and if I click on "Proceed" before they are calculated (the loading wheel is still rotating), the checkout page is loaded again and the user needs to reinsert the data.
I was wondering if I can disable the Enable button until when the shipping costs are shown, or if I can speed up their calculation (I actually have only 2 flat shipping rates.. very simple)
thanks
