The hassle I have is that the credit was passed about 6 months ago, and 
the payments have balanced out, but the negative value from 6 months ago 
isn't taken into account when payments were allocated since that date.

As a result, my payable aging looks like this:

30 days: R80.30
60 days: R0.00
90 days: R0.0
120 days+: R-80.30

And when I start up gnucash, I get a popup saying bills are due, when 
they are not.

Is there same way of clearing off this old negative amount? I'd rather 
not delete all the payments and then reraise them, as the accounts have 
been reconciled.

Any ideas?

Graham
