--- Comment #4 from Andrew Nguyen arethusa26@gmail.com 2010-05-25 14:41:17 --- If you start with a clean Wine prefix, and then install mdac28 and jet40 from an up-to-date winetricks (the mdac28 verb adds a native oledb32.dll override), does that change anything? Also, how do you compile your test program?
