[Opera-Linux] Problem with PDF files

[Sven]

Hi,

Running 9.64 on linux/KDE.

When browsing new/unread pdf-files it works fine with Acrobat reader 8/9. 
However, when browsing earlier read files I mostly (not always) have a blank 
screen only. The address in the address field is ok but the pdf do not load. 
Cut-and-past the address into Konqueror will open the pdf so the file is 
there.

Anyone having similar anoying problems ? Cache-problem ?

Thank's

Sven
