[GNC] Can't enter expense transactions after migrating

[Christopher Burnett]

After migrating to a new computer, all my data seems to be there and
visible in the accounts, but I cannot enter any new expense transactions.
I keep getting a "Save the changed transaction?" message whenever I put
values in the Withdrawal column.  Values entered in the Deposit column are
accepted. I updated to V 5.5 before migrating and am using V 5.5 on the new
Windows 11 computer.

Thank you!
