Please describe the problem:
When an invoice is created, under certain conditions, the invoice total will be
incorrect.

Steps to reproduce:
1. Create an invoice as described below.
2. The tax used in the example is 8.25%. 

Description Quantity Unit Price Taxable Subtotal Tax

Item one    1.00      43.29             43.29     0.00
Item two    1.00      60.00     X       60.00     4.95
Item three   .50      90.00     X       45.00     3.71
Item four    .25      90.00     X       22.50     1.86
Item five    .25      90.00     X       22.50     1.86

Total:$205.66  Subtotal:$193.29   Tax:$12.38
