crystal reports won't close Excel

I have a CR page that when run access Excel to get data. After it is printed the excel file remains open until I close my whole program. I have debugged the problem down to CR, so I know for sure that's where the problem is. I don't know the handle CR used to open it so I can't close it. I need to either know how to tell CR to close excel when it exits or a way to close a file when I don't know the handle used to open it. I have tried Excel.Application.Quit attached to the CR exit button and it didn't work.

It could be helpful if you post the relevant code

There is no code. I have a database set in CR to retrieve data. After I open and print the page CR won't release the database even after it's closed. Should I have some code in Cr ?
