Large Coupon Bug 1.3.0.2

I have 10 items in my cart with a total about of 116.33
Shipping 0
Discount coupon -81.35
Sales Tax is nonexistant after coupon code
Total -14.09

Here is the coupon information:
Coupon Amount :: 65.0000%
Start Date :: 11/30/2005
End Date :: 11/30/2007
Uses per Coupon :: Unlimited
Uses per Customer :: Unlimited
Valid Product List :: NONE
Valid Categories List :: NONE
Date Created :: 07/31/2006
Date Modified :: 07/31/2006

This worked on previous older version I was on.
Coupons with smaller discounts appear to be working ok.

Thanks!

Clean install or an upgrade to Zen Cart v1.3.0.2?

If an upgrade, what version were you and how did you do it?

Database was incrementally upgraded using sql upgrades in 1.3.0.2 package.

Zen Cart was copied from one working domain to my main domain's directories.... all base level files, then moved /admin and /includes. I didn't move any other directories.

I was at 1.2.5 before the upgrade

Thanks!

See if this sheds any light ...

Thanks! I changed Re-calculate tax to "none" and totals are coming out okay (except sales tax isn't on the subtotal - discount amount)

I also changed the sort order on the Order Total Modules.

It seems like the other two options have bugs associated with them as they either caused the incorrect order total or didn't recalculate sales tax based on the new total amount.

Thanks for your help!

What Order Total Modules are installed and what are the settings on each?
