XXL_FULL_API - closing message when closing Excel

Hi,

Would somebody be so kind and, please, clarify me why message in XXL_FULL_API is closed when user closes Excel?

It is command

message I233(SOFFICEINTEGRATION).

It is message 'Save the data in the spreadsheet' very well known to anybody who is transferring ALV to Excel (full aplication - not inplaced).

Debugger somehow changes behavior of function so message doesn’t close automatically.

Thanks to everybody.
