reporting and currency issues after 1.4 -> 1.6 upgrade

[waxmop@gtcinternet.com]

Howdy all -

I've been using the 1.4 version for about 4 months now and I recently
upgraded to 1.6 through Red Hat's up2date service.  I was able to open my
old 1.4 accounts just fine and all features seem to work except for
reporting.  

Now, when I choose any of the reports, the balance for all accounts is $0.
If I click "Options" and then under the "Display" tab, I click the "Show
Foreign Currencies. . ." option, then I get my accurate balances, but it
seems as if gnucash is converting my accounts into US dollars, even though
the accounts themselves are in US dollars.

I've checked all my accounts and they are all USD type AMEX, which seems
like the correct config.

Another detail I noticed is that my net worth is set to $0 USD.

Has anyone else run into this problem?  Also, I really liked the
heirarchical report available in 1.4.  Where is it in 1.6?

Thanks in advance.
