Default Bend Radius

Hi all,

   It seems that every time I create sheet metal parts my default bend radius changes.  It started out as 2mm, jumped up to 1300mm, back to 6mm and so on.  90% of the time I use only R 5mm.

   Is there somewhere in options where I can set this.  Alternatively is there something I am doing that is resetting the default while I am modelling?

Thanks

Oli
