tax calculation error with coupons

[poosk]

Ok so I made a coupon but it displays tax wrong in confirmations and bills..

€39.00
Sub-Total: €39.00
Code: xxxxx : -€5.84
Priority Mail (Shipping to FI (1 Boxes)): €3.00
VAT: €6.44
Total: €36.15

VAT tax is 22%.. Why the tax is calculated wrong?? should I alter the order total from admin? how?

By the way is there a way to move € sign after the price not before like you americans do..

I am having a similar problem on a client's store where the tax is not being calculated correctly when a coupon is used. I can't figure out what the basis for the tax calculation is and why it's miscalculating.

Anyone else have this problem?
