Version: (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages KNotes -> Settings -> Notes color: '&' is not escaped.
I don't see anything unusual in the settings window. Can you provide a screenshot please ?
Using Kubuntu 10.10 (kde 4.6.2) and master/branch 4.6 compiled from sources and using locales de/x-test/en_US I don't see the bug you reported. What is the locale you are using?
I am using the Romanian locale. However, this has not occurred anymore since at least KDE 4.4. I was using a beta version of KDE at the time of reporting this bug, so it was probably a temporary issue. This bug is no longer reproducible in the current version of KDE.
