XP, VFP7 and Excel 2000

I am having problems releasing the Excel object (process) after I have finished with the object. If I just create the object and then close again it works fine, but if I do anything like read a value or write to a sheet, in mosy instances it doesn't release the object properly (eg. If I use the Windows Taskmanager, the excel process will still be there).

I have read posts on this site, advising to ensure that I release the object after using oExcel.quit(), and even assigning null to the object variable, which I have followed to the letter, but still the process still hangs in the sytem.

Has anyone else any advise that may close the process after I have finished with it? Any help appreciated.

Regards
Darren
