Problems or changes to Microstation CE4

problems with CE4    with display style = hidden line     

1   transparency by element - not working, only transparency by level works.

2   printing to pdf - transparent objects no longer obey threshold setting in vector mode

will only obey threshold setting when in raster printing mode.

3  solids with line styles set to non-continuous only show as continuous even in wireframe.  

are these  problems or changes to the way MS CE  works?
