[GNC] Sales tax changes and posting an invoice wrong tax amounts

[Derek Atkins]

Hi,
This is not true.
Gnucash absolutely allows you to change the tax rates without affecting 
posted invoices.  When you post an invoice gnucash makes a read-only copy 
of the tax tables associated.  When you change it, it doesn't change the copy.

If you unpost an invoice it will ask you whether to keep the copied tax 
tables or revert to the current ones.  This let's you choose.

Happy Gnucashing!
