Discount with coupon calculates wrong total (OSCdox 2 RC2)

[itroxx]

hello there,

i have some problems with the OSCdox 2 RC2 and the coupon class (ot_coupon.php)

here the example of the checkout process

99.95 Cart value
-10.00 10% Coupon (9.995)
+5.00 Shipping (with tax 4.31/0.69)
------------------
13.10 (16% Tax/this is ok)
93.52 displayed Total (but the total should be 94.95)

The total order amount is calculated wrong. The tax of the coupon is deducted from the total and i don't know why.

For example the shopping cart ist 99.95 including 16% tax (86.16/13.79). I have defined a coupon for 10% off. The amout of the coupon is display right with 10.00 but the 1.38 coupon tax is deducted from the total but the total tax is calculated right.

I don't how to fix it. Appreciate any help. Thanks a lot
