invalid quotes leading to incorrect value for foreign stock

[Philippe A.]

I just solved a problem with the value of a foreign stock being incorrectly
reported in the balance sheet.

I had done mostly everything as explained here:
http://www.gnucash.org/docs/v2.6/C/gnucash-guide/currency_purchase1.htm
I live in Canada. My local currency is CAD.
My foreign stock is in USD.
I had  setup an USD bank account into which I had transferred money  with
the appropriate exchange rate.
>From the USD bank account I had recorded a stock purchase.
I had pulled the current exchange rate with the quote editor.
When I looked at the stock value in the balance sheet, it showed in CAD
with an incorrect value. It is like the exchange rate was not applied
correctly.
I have moved my US stock under the US bank account. That still did not
help. Even moving the USD account under the root did not help.

In the end I went in the quote editor and did some clean up for that stock.
I had many quotes from previous experiences, one of which was in my local
currency. After that the balance sheet started showing the right value.

The US stock does not need to be under the US bank account, possibly
because I recorded stock purchases in USD from the beginning.

I hope it will help someone.
