Hi there, I took a look at the Tk sourcecode, its limited by default .. see

http://cvs.sourceforge.net/viewcvs.py/tktoolkit/tk/generic/tkGrid.c?view=markup

//* * Data structures are allocated dynamically to support arbitrary 
sized * tables. However, the space is proportional to the highest 
numbered slot * with some non-default property. This limit is used to 
head off mistakes and * denial of service attacks by limiting the amount 
of storage required. *//
#*define* MAX_ELEMENT 10000

and

.\tkGrid.c:2216:   
  if (slot < 0 || slot >= MAX_ELEMENT) {
    return TCL_ERROR;
  }

Cheers,
