I noticed that in most of the recently posted builds, the "save changes" function in
TiddlyWiki no longer works. To see that for yourself, if you're not already a TiddlyWiki user, you'll need to save a local copy of TiddlyWiki and then try the "save changes" link. (It's a Wiki-like personal notebook implemented in HTML, CSS, and Javascript.)
By trial and error, i.e. downloading and installing many of the builds that have been posted to this forum, I determined that the last build in which TiddlyWiki works properly is K-MeleonCCF 0.020 PR8a. (Note: The "save changes" function doesn't seem to work in the stock K-Meleon 0.9 either.) By comparing the files in PR8a and PR9, I found that just replacing the chrome/en-US.jar file is sufficient to make "save changes" work. I've also been able to make it work in Guenter's WW0.9_1.7.8_2 and Fred's K-MeleonWW0.9_1.7.8-modified by replacing chrome/en-US.jar, although that makes the about: page look a little weird.
When TiddlyWiki's "save changes" works, what you'll see is an Internet Security popup saying that a script is requesting enhanced abilities. I think that popup is missing from the chrome/en-US.jar files in the recent builds. Anyway, I'm posting the information here in case anyone can step in and figure out what went wrong.
