I also have an intermittent problem with exports on a Mac. It seems to be buggy if there are any 'null' cells. When I am having trouble I seem to be able to get it to be able to get it to work by putting some sort of value in place of nulls. (I use a dash in text columns and a 0 in number columns.) For some reason it doesn't happen with all recordsets. Today I am exporting a recordset loaded with nulls. Its a real pain but when I get desperate I trap all of my nulls in the query with an ifnull statement.
