Looks like I just joined the club.
I'm running 4.5 on a G3/233 - well, I use the term "running" in its loosest sense. More like crawling.
But it won't run on my "new" (just bought) G4/400 with 1Gb of RAM installed.
Error type 1, like everyone else.
FaxSTF application appears to be installed but there's no control panel.
I let LW install the latest Java thingy. Maybe that was a mistake?
Ho hum. Back to the G3. I'll put the kettle on.
