We has a new PC with Intel "core 2 duo" CPU and Windows XP SP2 in it. This PC has very old version of ORACLE client 8.06 and ORACLE developer 6.1 (Forms, reports) in it. When we run "sqlplus" (version 8.0.6), we get MS Windows pop up error. I look detail messages and look like it stop on "kernel32.dll". Does anyone have similar problem "core 2 duo" and old version ORACLE client? Does this error come from "core 2 duo"? Thanks. --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.
