Reading DBC header repeatedly?

Hello. I just did a file system trace on our network VFP app using filemon from www.sysinternals.com, and though I didn't solve the problem at hand, I did find something very interesting. For some reason, VFP is reading the header of the network DBC(no views in it) repeatedly. Out of 13,851 network file operations that take place when starting our application, 10,041 are simply reading the first 32 bytes of the DBC. That's 72.5% of the file operations!!! Looking at the structure of a DBC/DBF header(type, last update, reccount, first data record position, length of data record, reserved, table flags, code page, reserved), I can't understand why my VFP app would be reading this so often. Any idea what this could be and how to stop it? Thanks.
