<p class="yiv0937220347MsoNormal">12 out of our 20 vitrines are exhibiting gaping at the sides, top, base, or all seams. There does not appear to be any one pattern. All cases are in the same room, some along walls, some centrally located. We do use a data logger and I
am hoping that will provide some clues, but I would truly appreciate any thoughts any of you might have. <u></u><u></u></p>
