Drawing view dissapears when changed to hidden lines removed

So when I insert a rather large view of an assembly and useanyview other than hidden lines removed all is good.  WhenIclick hidden lines removed, it changes over for about 10secondsand is perfect, then dissapears.  What is up withthat?TIA
