Also noticed the translator.library SYS:Prefs icon is still old style 2 colour OS3.0/1.
It needs updating to the Glowicon standard in order to blend in with OS3.9's other prefs icons.
I also had an issue with AHI prefs not working when double clicked. Something about a wrong version? Might be a fault my end though, so I'll test it on a clean OS39 install.
