In an application I am attempting to write, I have a dialog with one
edittext item (item 2).  When the dialog is requested from the menu,
the routine starts with:

char strbuf[60];
GetDItem(dialog, 2, handle);
/* set the string at strbuf+1 to the desired display */
trbuf[0] = strlen(strbuf+1);
SetIText(handle, strbuf);

Then I enter a loop:

do {
	ModalDialog(dialog, &theItem);
	if (theItem == 2) {
		GetDItem(dialog, theItem, handle);
		GetIText(handle, strbuf);
		/* process input */
	}
} while (theItem != 1 && tehItem != exititem);

This all works fine the first time I call it.  However,
the second time, the whole system hands.
If I run with LSC breakpoints inside this routine, it runs most of the
time.

I presume I am causing some kind of wandering memory reference.
What?

Any Comments or suggestions would be appreciated.

p.s.	obvious errors in the above may be due to not having the
code in front of me, or may be due to my having not understood
what I am supposed to do.  Thanks in all cases.
