eap 24fe0efaab IPAL52827: Very few filtering criteria available in filter dialog called from Remove Elements dialog
IPAL52831: Veeery long awaiting for Mesh Information dialog appearance
IPAL52822: Find Elements By Point does not find coincident nodes
IPAL52821: Find Elements By Point dialog: no types available for search if there are only nodes in the mesh
IPAL52823: mesh.GetSubMeshElementsId( subShape ) works wrong if subShape is retrieved indirectly
