Hare Rama! Hare Krishna!

If the crystals are dissolving as described, I would try one 
of two things:

1)Mount them without the mother liquor/storage solution?

2)Use a longer capillary,  one end of which contains a plug of 
  suitable dehydrant, solid or liquid. If the dehydrant dries
  up the crystal too soon, use a wider (1.5mm) capillary and/or
  have an "isthmus" between the dehydrant and the crystal.
