Quick Reports - Crystal Reports, MetaFiles (filters) , Printing and Preview

Hi I have Some Quick Report Questions
  1) should I be using Crystal Reports?
2) I have been using The Filtering for export to export the reports
(html, rtf, excel) and they all sort of work except the metafile which
crashes and burns, any thoughts?
3) I'm using the TQRPreview to display the report at run time and I have
been having a lot of fun making the preview flow and size properly.  I
doen't seem to be the sizing of the actual preview but the size of the
"panel"? it is in that is a bit iffy, any comments?

Thanks Roger
