Duplicate Paypal orders

I have been randomly getting duplicate orders show up when people pay with Paypal. The payment is only received once as it should be but two of the same orders show up a couple seconds apart. Not sure what is going on, need some input.

I've seen it happen in some cases when PDT has been enabled when using the Website Payments Standard(IPN) module.

One can also avoid the problem by turning off Website Payments Standard and using Express Checkout instead.

I'm also having some random duplicate orders... What is express checkout? Is that a mod that one needs to install? I do see a PayPal Express checkout. Does anything else have to be done other than enabling the paypal express and disabling the other? Can you tell me what is the difference between the two?

Thanks

I also have the same problem.

is paypal express available for zen 1.3.7? that is the one I have installed and right now I do not have time to do the upgrade to 1.3.8 ( I had added several mods):lookaroun

PayPal Express Checkout is available as far back as v1.3.7.1.
