I ust got another PDF file online. It is a manual for a receiver. I am running a P4 with 1 gig memory and every PDF file I've ever used slows my system down to a crawl when I click on it. Same for work or any other PC I use. Broadband connections seem to help, but it is still a problem. Then, when I think it is downloaded and I try to scroll, my system slows again.. I hate those goddam memory munchers! I have to download and save them, then, after a considerable wait for the download, I can finally view them at a reasonable speed. So why the F are PDFs so friggin popular?
