Dear Steve: It seems that the mounting media you used retracts with the time. This kind of artifact i have seen working with sinthetic mounting media that has no tolerance for heat and, in other cases, with aging. Try to find an adecquate medium, I proved with success Clarion from Biomeda, and I have slides mounted with it that have no changes -no bubbles,no retraction no cristalization- after many years. Good luck,Carlos
