Problem adding account to existing accounts

[Leslie Katz]

I have a file containing a number of accounts, each of which represents 
an individual security. I needed, and got, help from the list when 
creating the file.

Now, I need to add another account to the existing ones and I've 
forgotten everything I did at the outset.

I'm trying to follow the instructions in the guide called "Example Stock 
Account" (s 8.4.2). They say to click on File, New Account, to get the 
New Account dialogue. Next, name the account, using the stock ticker 
abbreviation. Next, click on Select next to the Commodity line, which 
will bring up the Select currency/security dialogue. Up to there, no 
problem.

Next, change the Commodity type from Currency to, eg, NASDAQ. I can't 
achieve that using the Select currency/security dialogue. I can 
highlight the word Currency, but I can't alter it in any way. The drop 
down menu contains no other option than Currency. How am I supposed to 
change it to, I assume in my case, ASX (the exchange on which the 
security's traded)?
