Hi All
I have an Artixscan 4000t  which has caused many headaches.  I use a 
MAC and have OS 10.3 (Panther) on my machines.  Although we have 
downloaded the drivers for the OS X from the Artix website  they have 
been so unreliable that we have had to reinstall OS 9 just to run the 
scanner.  I have just heard that SilverFast have released v6 software 
which they claim will support the Artixscan 4000t.  Before I download a 
demo version to try I am interested to know if anyone else has used the 
SilverFast software and how they have found it.
Cheers
Trish
