Gear mesh add-on (2.60.5)

When I first add a gear mesh (or any other new mesh), a group of settings appear over on the left side of the screen, but once I deselect the object, those settings disappear and I can’t find them again.

Can they be found somewhere else? Thanks for any clues.

these setting are met to be changed only while creating the new gear!

ou ce you de select the object then their gone!
