Excel not closing or releasing

Does anyone have an idea why the excel object does not close here?

xlWorkbook.Save 'save as current

xlWorkbook.SaveAs(xlFileName) 'save as MM_DD_YY_Time+filename

xlApp.Quit '// Close Excel

Set xlApp = Nothing 'release memory

I’m all out of ideas. This code should be hit everytime and there is only one object we’re dealing with.

Thanks for any ideas…
