can you get the Clone to work if you hard-code the rectangle to say {0, 0, 50, 50}?

unless tmpPnl is a member of the pictureBox.Controls collection, it's bounds are likely to be relative to the pictureBox.Parent control

TransparentPanel tmpPnl = e.ClickedItem.Tag as TransparentPanel;

Rectangle rec1 = base.Controls[tmpPnl.Name].Bounds;
Rectangle rec2 = tmpPnl.Bounds;
