If this is a multi-user site then you have the classic symptoms of Opportunistic Locking being enabled when it should be disabled. To check and disable Opportunistic Locking run x:\softrak\system\chksys.exe (where X is your server drive).
If not then it could be something as simple as installing a missing service pack.
You will also likley have data corruption which must be fixed. If Steve's instructions find errors that require an expert to fix then you should contact your Adagio dealer for assistance. If Rebuild is able to fix the error you should alway rerun it until it checks without finding any errors.
Even if data integrity is clean you will have problems with your data that must be addressed (checks posted to the wrong vendor). Again assistance from your dealer would help you resolve these quickly.
