I am getting the following X toolkit warning:

X Toolkit Warning: 
    Name: text5
    Class: XmText
    Invalid margin height, must be >= 0.

after the following piece of code has been executed several times in
a loop:

XtSetArg (args[0], XmNvalue, temp_holder_two);
XtSetValues( LOCKtoTPT_Text, args, 1);

where temp_holder_two is an array of 71 characters which never contains
newlines (if that makes a difference), only reg. alpha-numeric characters and 
an occassional ^M (carriage return character)

and where LOCKtoTPT_Text is an XmText widget created as follows:

    n = 0;
    XtSetArg (args[n], XmNcolumns, 70 );  n++;
    XtSetArg (args[n], XmNmarginHeight, 3 );  n++;     /* default */
    XtSetArg (args[n], XmNeditMode, XmSINGLE_LINE_EDIT);  n++; 
    XtSetArg (args[n], XmNeditable, FALSE); n++;
    XtSetArg (args[n], XmNcursorPositionVisible, False); n++;
    XtSetArg (args[n], XmNfontList, fontlist6x12); n++;
    LOCKtoTPT_Text = XmCreateText (line, "text5", args, n);
    

I inserted the following code after the XtSetValues to find out the
value of the marginHeight resource:

XtSetArg (args[0], XmNmarginHeight, &margin_height);
XtGetValues( LOCKtoTPT_Text, args, 1);
printf("text5.marginHeight: %d\n",margin_height);

and I got the following output for several iterations of the loop:

text5.marginHeight: 15
text5.marginHeight: 23
text5.marginHeight: 31
text5.marginHeight: 39
text5.marginHeight: 47
text5.marginHeight: 55
text5.marginHeight: 63
text5.marginHeight: 71
text5.marginHeight: 87
text5.marginHeight: 95
text5.marginHeight: 103
text5.marginHeight: 111
text5.marginHeight: 119
text5.marginHeight: 127
text5.marginHeight: 135
text5.marginHeight: 143
text5.marginHeight: 159
text5.marginHeight: 167
text5.marginHeight: 175
text5.marginHeight: 183
text5.marginHeight: 191
text5.marginHeight: 199
text5.marginHeight: 207
text5.marginHeight: 215

  and so on...., starting at 15 (why?) and always increasing by 8. 

The value probably eventually execeeded 2^^16 (the resource's type is a
short int) and at which point I get the X toolkit warnings, which slow
my application down and fills up my xterm from which I started the 
application.

Any ideas what might be causing this problem??  What am I doing to 
increase this resource value and how can I prevent it so I don't get
the zillions of warning messages??

Thanks In Advance
