delete/move multiple entities in Draftsight

have recently downloaded DraftSight 32 bit on Win 7 as a substitute for AutoCad

the most annoying feature is the inability to delete or move MULTILPLE ENTITIES [AutoCad does it ok]

unless you use the window command which is not always usable as it deletes/moves everything with the window

only command available is single select option

does anyone know how to programme the mouse for mutilple LC operation ?

otherwise a fine alternative to AutoCad
