Clicking "Show Preview" is the same as toggling between Generic and Classic Mode. Clicking "Show Changes" always goes to Classic Mode.
FYI, I've found the source of this bug and applied this patch. Looks like some php installations will set switch-mode even if it's submitted empty. @@ -705,7 +707,7 @@ * pressing the "switch mode" button, then * set a global to do some jiggery-pokery * in the displayEditPage function, later */ - if ( isset( $data['switch-mode'] ) ) + if ( isset( $data['switch-mode'] ) and strlen( $data['switch-mode']) > 0) $wgSwitchMode = true;
mikel's patch has been applied in rev #48098, not sure if i should mark this as closed yet...
This bug is fixed in trunk.
