Quick report 3.0

Help......

I'm using quick report 3.0 ( supplied with Delphi 4.0 ) and I can' find the
answers to the two problems..

Can anyone help ???

1. After adding the CSV and TXT file filters , how can I make one of these
the default save extention rather than the *.QRT

2. The close button on the report.preview bar does not return the focus to
the calling form ( report forms are created at run time and then destroyed
on close )

Thanks In advance
