As you say, that's all very standard.
There's a couple of things that A2007 does oddly.
One is that it fails on an expression such as:
=[Form].[RecordsetClone].[RecordCount]
If you have any controls on the form that contain an expression (starts with
"="), try deleting those controls temporarily. (There's a situation where
Access quits trying to calcluate controls once one fails. That's why it's
important to delete all calculated controls to eliminate this possibility.)
There is also an issue where the AccessField type can confuse Access. If any
of the names in LinkChildFields or LinkMasterFields is not a control name,
clear the properties, add a text box for that control, save, and then set
the LinkChildFields/LinkMasterFields properties to the name of the control.
Turning off Name AutoCorrect may help also:
Office Button | Access Options | Current Database | Name AutoCorrect
As you are switching versions, it may help to compact, decompile, and
compact again.
You say the form is bound directly to the table, so it cannot be a cyclical
reference to something in a query.
Presumably your References are all okay.
You might also clear any input mask, format, and default value from the
control on the form and also from the field in the table, to eliminate that
possibility also.
Hopefully something there leads you in a useful direction.

Another possibility is if the Name property of the text box is the same as
the name of something else.
