Hi Rolf
Had the same problem, found & remed out this code, at the bottom of the setallprop method of txtbtns class.
************************************
CASE ATC(m.oControlParent.Controls[m.i].BaseClass,"Grid") # 0
* removed by s ramsey
* m.oControlParent.Controls[m.i].ReadOnly = !THIS.EditMode
* m.oControlParent.Controls[m.i].DeleteMark = THIS.EditMode

ENDCASE
