FLAT RATE SHIPPING

Is this the default behaviour for Flat Rate shipping, to show "Calculated during checkout" :

Sub-Total:   $39.95
Shipping:   Calculated during checkout
Tax:   $0.00
Total:   Calculated during checkout

or am I doing something wrong? I can only get it to work when a user logs in or registers.

I added "Free Shipping over $99.00", and it doesn't show "Calculated during checkout"
when the user is not logged in or registered, it shows the updated shipping price right away:

Sub-Total:  $161.75
Shipping:   $0.00
Tax:   $0.00
Total:   $161.75

There has to be a way to get the Flat Shipping rate to do this too.
I have to change it so it calculates the flat rate shipping for any user : Anonymous or Registered,
but don't know how to do it.

I think changing this line in OrderTotals.ascx.cs  would do it :

   bool shoppingCartRequiresShipping = this.ShippingService.ShoppingCartRequiresShipping(cart);
                if (shoppingCartRequiresShipping)
                {
                    decimal? shoppingCartShippingBase = this.ShippingService.GetShoppingCartShippingTotal(cart, NopContext.Current.User);
                    if (shoppingCartShippingBase.HasValue)
                    {
                     ..............

How would I pass in all users instead of Current?

had the same problem !
you have to "enable" this shipping method for the countries you like to allow it.
this means the field MUSN´T be markered !!!! I markered but this means DONT allow
this shipping method in this country
