|X Toolkit Warning:

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

|    n = 0;
|    XtSetArg (args[n], XmNcolumns, 70 );  n++;
|    XtSetArg (args[n], XmNmarginHeight, 3 );  n++;     /* default */

|    XtSetArg (args[n], XmNcursorPositionVisible, False); n++;
|    XtSetArg (args[n], XmNfontList, fontlist6x12); n++;
|    LOCKtoTPT_Text = XmCreateText (line, "text5", args, n);

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

	If in part what you are asking (which I doubt) is
	"Why do I get the toolkit error."
	that's because the marginHeight value is rolling over into
	the negative domain.
	Why the marginHeight value is getting changed,
	I don't know, but you might try not putting in the ^M,
	they might be screwing up the single-line-edit mode.
