To delete an investment from lists, shares held must be zero. Blank the symbol
in details and change name to something weird. If you delete
an investment, your net worth over time report may be affected.
Deleting an investment does not fully delete it from your file
Go to the Portfolio. (Create a Shortcut if you don't have one)
Portfolio->WorkWithInvestments->DeleteAnInvestment
Ones in gray cannot be deleted currently, but the ones in darker text can be deleted.
