dashCommerce

I have gotten the project working just fine on my local box (to display, checkout, and payment, etc...). The whole time I'm developing on my local, the application is pointing to the database on the production server, it works perfectly fine.  But the moment that I moved the web folder to the production environment, the process of filling out the billing/shipping information prior to be redirected to paypal site is not working, the "Continue" button does not advance to the next step (whether ShippingAddress/Shipping method), the "Updating Order . . ." promps appear indefinitely.  I found the exact same behavior on the demo site of dashcommerce at http://www.dashcommerce.com/.

 Does anyone have any ideas as to what causes this?  I really appreciate that greatly.  thank you.

This isn't happening at http://www.dashcommerce.com - I'm getting orders - did you mean the demo site @ http://demo.dashcommerce.org?

Thanks for pointing that out.  Actually I have that problem on the machine I use for developing (The OS is window server 2003), but I test on another laptop running Window Vista, I'm getting orders, no problem with the "Updating Order" appeared indefinitely.  Do you know what causes one of my machine have that problem (especially the one that I use for developing...).  Thank you again, I greatly appreciate it. 

 Maybe this is a JavaScript problem

thank you for pointing me to the right direction.  It is a javascript related issue, since my os is window 2003, I have to disable the Internet Explorer Enhanced Security Configuration.
