Their Flash PDF reader also doesn't work at all on any of the Linux boxes I use. It actually got majorly worse when they made it less shitty on other platforms -- it doesn't accept mouse clicks at all!

They sent me an email and we had a long conversation with after I slagged on their reader here before, but the general conclusion was that they didn't view the Flash app as their core competency -- they're a community site, damnit!

I use the brilliant http://docs.google.com/viewer and I have no idea why the hell Scribd doesn't clone it.
