Can you please confirm which version of SQL Dependency Tracker you are using? If it is not the latest patched version, can you please try using that and let me know how you get on? The patched version is available from the below link:

With regards to field dependencies, this isn't something that is available within the tool however we are going to be introducing column level dependencies with the next version of our SQL Prompt tool, version 5 so you may wish to take a look at the EAP for that which is also on these forums.
