You could check that the problem does not occur with sample.mny.
That typically resides in "C:\Program Files\Microsoft Money 2005" or
"C:\Program Files (x86)\Microsoft Money 2005"
Assuming the problem does not occur with that file, I would return
to your regular Money file (you can use the list at the bottom of
File). I would start with File->RepairMoneyFile->QuickFileRepair
If the problem continues,
File->RepairMoneyFile->StandardFileRepair level 2
If the problem persists,
File->RepairMoneyFile->StandardFileRepair level 1
