Hi Michael,

I've been using the 'R' key for the shortcut for 'Rebuild', so I thought, but in checking my shortcut key's it so happens that the command wasn't 'Rebuild' in was actually 'RebuildCurve'
which has carried on from version to version this was before you put the official 'Rebuild' in place, all is good now :)

Cheers
