Problems with Pdf files

["Percy"]

Hi guys I'm new with Opera and I have a little problem with pdf attachments 
when I wanna print them directly from the e-mail client without save them 
into the hard disk  it only prints a blank page if I save them into the hard 
disk it prints all. I've changed from Acrobat reader 6 to 7 but the error 
remains.
I have win 2K pro, spk4 and  Opera 9.0.1

Thanks

PERCY
