>My program is not being released from memory when the program exits. Obviously, there must be a unreleased object reference somewhere but the program is somewhat big and I can't seem to locate where the problem is. Can someone share how I can go about more easily finding the unreleased object reference? TIA.

There is no easy way in Visual Basic. I would look at any activex controls you use and any multi-threading code.
Also, make sure you actually close every Form and set the references to NOTHING.

Look for state-machine code that could run continously also, since that will lock a Form open but hidden.

Good luck!
