Re: Scidavis and Kompozer in Fedora 17 (problems!)
Can't say about Kompozer, but SciDavis' disappearance was troubling, since I had many files that I used in teaching.
A work around: believe it or not, I was able to install SciDavis for Windoze under Wine -- the Win installer even reached out to install Python 2.6 for Windows (necessary for SciDavis). Very tidy! Font is a bit off -- but files seems to load and work.
