I have Personal Finance 2.0.8 and there seems to be problems with the Balance Account dialog.
I checked the "show reconciled" box and that cleared all of my bank entries as reconciled - even though I was only part-way through. I could not go back - unchecking the box made no difference. I also tried unchecking individual items in the dialog, but when going back to the main account screen they were still shown as reconciled.
Is this a fault ?
Also - in the main account screen I resorted to right-clicking the entries and removing the reconciled status. But that was a pain as after each un-check the cursur went straight to the first account entry each time. Annoying, but not as bad as the reconcile dialog.
