VBA Automation Error when Cancelling Macro in eGlobal

Minor annoying issue.  Curious if someone could shed some light on it....

I have a number of macros deployed to eGlobal in Project Server 2010.  They all work fine.  When I give the user an option to cancel the macro in a MsgBox, the macro cancels but displays an "Automation Error" message before cancelling.

I don't recall seeing this behavior prior to pushing the macros to eGlobal.

Is this just an error handling issue?  How can I get the macro to cancel gracefully?

Thanks in advance...
