After a lot of trying, I just can't get this to work (under Snow Leopard on a MacBook Air, using the latest version of DockSpaces, 3.01).

I've linked my docks to different spaces, but each time I change one dock, all the others change -- even if I specifically load one dock, make changes to it, then load the next, change it, etc. As soon as I change Spaces, the dock messes up, with dock #2 becoming dock #1, and so on. So I correct all the docks, and as soon as I switch Spaces again... a mess. My Work dock is now my Play dock from two sets of changes ago, etc.

This is a beautiful app, and the theory of how it works is great, but in practice I can't get it to behave as it says it will.

It seems to be working for others, though :(

I've used GoogaLoom, PayLoom, and now RapidCart. RapidCart blows the other two away, because it doesn't require users to interact with an unexplained pop-up PayPal window every time they add something to their cart. Instead, items' icons swoosh up into the cart icon, and all the shopping cart functions are integrated into the page, hovering there (through Ajax or whatever magic is running it).

I switched to this plug-in and am very happy with it. I think it provides a much more graphically polished and pleasing look on my site, and must inspire more confidence in users because of the visually self-evident way it carries out the shopper's selections.

It also allows for pop-up menus that change each item's features; my only wish is that these could affect the price (so I could have users choose local or international shipping, for instance, instead of having to host two separate shops on my site).
