SendObject Hanging up database

[Cathy]

I've written a sendobject that hangs up the database. Once it sends the
e-mail, the screen turns black and will not return. Can you see anything
wrong with the code that would cause this? Any recommendation on how to fix
this?

DoCmd.SendObject acSendTable, "MJEP_Approvals", acFormatXLS,
Forms!frmProcessControlApprovals.User_ID & "@dtenergy.com", _
"", "", "MJEP Approvals", "See the attached list of approvals processed
via the MJEP Database.", True, ""

Thanks!
