	There is an interesting bug in TESetSelect.  If it is called before
	TEClick is ever called, the selection region is set to the proper
	value, but the caret appears at the end of the previous line if
	it was intended to appear at the beginning of a line.  Of course
	this causes strange things to happen when something is inserted
	(an in TEKey).  There is an interesting kludge which I added to
	solve this problem: (using MegaMax C)

		if	((*hte)->clickstuff == 0)
			(*hte)->clickstuff = -1;
		tesetselect	(start, end, hte);
	
	I discovered this is because clickstuff always has a value of
	-1, -255, -256, 255, and 256, but 0 before any text operations
	have been performed.  I arbitrarily chose to assign the value
	of -1, since this is the most common.  Question:  can this
	have any harmful side effects?  Also, what does this field
	mean, anyway?
