I've assumed that 32-bit binaries run OK on 64-bit Windows -- is that not right? One obstacle to building a 64-bit gretl distribution for Windows is that this would require (I suppose) a 64-bit build of the GTK stack. I'm not cross-building GTK (very tricky) but just using what's available from gtk.org. There is currently a 64-bit build [ http://www.gtk.org/download/win64.php ] but it's labeled "Note that these 64-bit packages are experimental. Binary compatibility between versions is not guaranteed." Ergo, I'm not going to mess with this until somebody makes a convincing case that it's a necessity. Allin
