In one of my personal checking accounts (my main checking account) in
the ledger screen, the Balance column is showing a completely
different amount than what is actually totalled up. In the Home
Screen, in reports and elsewhere, it shows the correct balance. And
it's only this account, no others are affected that I can see. How can
I fix this? And is all my data and amounts alright? FWIW, the
reconciliation this month for the previous balance was incorrect, show
I simply changed it according to my bank statement. This is v0.9.2
from the default repos of Ubuntu 9.04 x64 edition under the Gnome
desktop. Thanks in advance!

version 0.9.2 had a problem with reconciliation. Please upgrade to a newer version.
