data entry using 2k7 not viewable in 2k7 but is viewable in 2k3

[primetime]

I have a user with a database that was created in Access 2k3. When we updated the users Office suite to 2k7 everything was functioning properly except certain Access databases. The database in question is stored on a network share and is ~100MB in size. When the user opens that database all of the forms open and data can be entered. Once entered and saved the new data is no longer viewable in Access 2k7. If you go to another machine and pull up the database using Access 2k3 the data that was entered in Access 2k7 is viewable. again the issue is data entered in Access 2k7 is not viewable in 2k7 but can be viewed in Access 2k3. any thoughts on what might cause this behavior?thanks in advance for your help.
