Replicate w/ rotate of graphic item doesn't work.

[yoy]

I've drawn a line (graphic object) and it's selected. I go to
Edit->Replicate menu to replicate it three times with 0 offsets, and want to
rotate each replication 45 degrees (a simple "scope" crosshair indicator)
but the Rotate field is dimmed.

What's wrong here (Win2k/Rev 2.1)?

TIA,

Andy
