I am using a very hand Notepad application TiddleWiki (
www.tiddlywiki.com) with OmniWeb which was working fine.
In order to write to your local disk this (java script) app uses a *.jar certificate file which needs to be trusted by your browser.
Since I updated to Java 1.6.0_29-b11 from Apple OW refuses the certificate no matter what kind of settings I have in my keyring or with the Java prefs.
Safari works fine here, Firefox too, its just OW which breaks.
