How does one change the number of decimal places in stock account?

[Richard Dawson]

I have an existing account that displays five decimal places in the number of 
shares column.  The company holding the account has now changed to 6 decimal 
places, and I would like to keep my tally equal to the tally on my statements.  

So, I edited the account and changed the "smallest fraction" setting from "Use 
Commodity Value" to 1/1000000.  I then attempted an entry.  All seemed OK, 
except when I completed the entry it refused to update the running balance.  
It just leaves the balance field blank.  

I set the smallest fraction back to Commodity Value, and I was able to add 
entries and see the balance increment accordingly.

How can I change the number of decimals displayed for Shares added in a 
transaction and for the running blance of shares?

You may wonder why one should fuss so much over a few millionths of a share, 
but when your total number of shares is as small as mine a few millionths is 
important!

Thank you,
