Deleting a voided transaction

[Heather Daley]

I have one transaction that was previously voided (and reconciled.)  I 
would like to delete it, but gnucash calls it read-only and will not allow 
me to edit it at all.
The underlying problem here is that I'd really like to delete the whole 
account, but it will not delete all the transactions because there is a 
read-only transaction in the lot.  And there are hundreds of transactions 
- I'd really rather not delete them individually by hand.

thanks,
Heather Daley
