Hi Charlie
I had it also in the past
in the declaration you use Object, and that has no .delete !

use for the variable in global section 
Public hFldTableView as TableView

and button1_click
hFldTableView = NEW TableView(Frame2) AS "FldTableView"
hFldTableView is a handle to it and the AS "FldTableView" is the name for it

--------------------
' Gambas class file

PUBLIC hFldTableView AS TableView

PUBLIC SUB Button1_Click()

IF hFldTableView=NULL THEN
  hFldTableView= NEW TableView(ME) AS "FldTableView"
  ENDIF
  hFldTableView.Move(0,0,50,50)
endif
END

PUBLIC SUB Button2_Click()
  IF hFldTableView<>NULL THEN
    hFldTableView.delete
    hFldTableView=NULL
  END IF  
END
-------------------------

I'm afraid you .delete the FldTableView as name and you want the object

I tested this and it works for me
