I just bought an eBook from DrivethruRPG, but Adobe Reader lags when I scroll down. It's like, as it tries to load the rest of the page, rather than smoothly processing it, it loads in chunks. Are there any good alternatives to Reader?

-edit- Anyone here recommend FoxIt?

Yeah just found out about it too, but some WOT users say it installs the Ask toolbar even if you uncheck it. Does it? I'm rather paranoid about this sort of thing.

Nope, unchecking that keeps the Ask toolbar away.

Hey thanks for recommending Sumatra. It's awesome.

Btw is there any way to increase the rendering speed ahead of time?

What version of Adobe Reader, the latest one?

I recommend PDF X-Change. I prefer it over Foxit and Sumatra.

Same here. Fast and many good free features. There is also a free pdf-printer for non-commercial use.

I use Foxit for viewing, PDF X-change for editing, and Adobe only as a last resort. Should try Sumatra, though, it looks like. :)
