OK, so this is effectively the same WM_NORMAL_HINTS setting as above
except that now it works.

It seems that the min/max size setting is "sticky", i.e. once the
WM_NORMAL_HINTS property is given a min/max size, it persists even
after after the property is changed back.

Try replacing the lines:

	szhints->flags = PSize;
	szhints->width       = xwa.width;
	szhints->height      = xwa.height;
	szhints->min_width   = xwa.width;
	szhints->min_height  = xwa.height;
	szhints->max_width   = xwa.width;
	szhints->max_height  = xwa.height;

	if (minmax)
		szhints->flags |= PMinSize | PMaxSize;

with:

	szhints->flags = PSize | PMinSize | PMaxSize;
	szhints->width       = xwa.width;
	szhints->height      = xwa.height;
	if (minmax)
	{
		szhints->min_width   = xwa.width;
		szhints->min_height  = xwa.height;
		szhints->max_width   = xwa.width;
		szhints->max_height  = xwa.height;
	}
	else
	{
		szhints->min_width   = 0;
		szhints->min_height  = 0;
		szhints->max_width   = DisplayWidth(dpy, scrn);
		szhints->max_height  = DisplayHeight(dpy, scrn);
	}

If this works, can you also check that "maximising" the window works
correctly (i.e. it doesn't result in a window which is larger than the
screen).
