Wrong decimal value (0) when after longtext field in select clausule (using ADO, client side cursor)

ODBC connector 3.0.3 returns always value 0 for decimal fields when accessed via ADODB with clientside cursor when decimal field is after longtext field in select clausule .e.g:

vb6 code
set conn = new ADODB.Connection
set rs = new ADODB.Recordset
rs.CursorLocation = adUseClient
conn.Open "DRIVER=

;SERVER=...;DATABASE=...;UID=...;PWD=...; OPTION=3;"
conn.execute "create table aaa(nm_price decimal(20,4), m_comment longtext)"
conn.execute "insert into aaa values(123.45, 'xxx')"
rs.Open "SELECT m_comment, nm_price from aaa", conn, adOpenForwardOnly, adLockReadOnly
MsgBox rs.Collect("nm_price") ' = 0 - ERROR
rs.Close
rs.Open "SELECT nm_price from aaa", conn, adOpenForwardOnly, adLockReadOnly
MsgBox rs.Collect("nm_price") ' = 123.45 - OK
rs.Close
set rs=nothing
conn.execute "drop table aaa"
conn.Close
set conn = nothing
