I have my monitor modes set up manually in tooltypes as I have for ages now. And also for low res modes I use. However now these don't work and OS4 claims the monitor doesn't support it! Obviously this isn't true. And what's worse it mucks up all my MUI settings! My Internet apps keep appearing on my Workbench because the modes are not created anymore.
In the Montors tab of ScreenMode Prefs I have Detect off. My VSyncs are locked to 60Hz. Horizontal set to 31000 and 85000. Why does it think these modes are incompatible now?
