When I like to print an envelope I do like this in Word 2003:
Select Tools - Envelopes and Labels... in the menu.
Select the Envelope size C5.
Type a delivery address.
Click the Options button and change
From left from Auto to maximum
using the up arrow button (12.71 cm), and click OK.

I click at the print button and the resulting printout has the adress
printed 9.7 cm from the left (3 cm wrong).

Why cannot Word print correctly ?

If I set From left to 5.0 cm the address will be printed correctly 5 cm from
the left edge.

Next time I do:
Select Tools - Envelopes and Labels... in the menu and click the Options
button, the From left setting is back to Auto.

Why cannot Word remember my last settings ?
