You didn't indicate your platform. There's at least one other open source viewer for Linux (xpdf), but I'm not on Linux and so have no experience with it. In the Windows world (and on Macs and I guess Linux) you can use Adobe's Acrobat Reader, but you won't have an easy time seeing updates under Windows, partly because there's apparently not a good way to signal Reader that the file has changed and partly because, under Windows, it locks the file so that it *can't* change. LyX reports an error if you try to update using pdflatex while the original version is loaded in Reader, due to the file lock; if you close the PDF file but leave Reader open, Reader complains it can't find the new file (even though it's where it should be, and it can be opened from Reader's file menu). -- Paul
