--- Comment #9 from Hans Leidekker hans@meelstraat.net --- I think the confusion stems from the fact that if you run 'wine regedit 123.reg' the 32-bit view will be updated, but if you run 'wine regedit' and then import the same file through the menu, the 64-bit view is updated. This is because the former doesn't restart regedit as 64-bit.
