Marketpress - 'buy now' links from global widget / tag cloud don't work

Not sure if this is an error that was fixed as I'm still using 1.1.3.

Off topic, but will 1.1.6 work fine with 3.0.4 or is it more for 3.1?

Back to the problem...

When I click on a product from the Global product tag cloud or the Global product categories, I end up on the users product ok, although it's not on their store, but on the main site store.

That's great, but when you click on 'buy now', it doesnt redirect, it simply refreshes the page.

Couldnt find the same problem elsewhere here, not sure if its permalinks related?

Thanks,

George
