I just opened Max 5.1.8 after a few months and my patch screens have no type - also the preference screens in Max are blank.

I have no idea what this is. Could it be the default color has been set to white? And if so, how would I fix it when the prefs are also blank??

Also discovered that when I open "fonts" inside Max, the type is set to white. And when I change it to black it reverts to white - as if it's locked...

Fixed. Went to Library / Preferences / and deleted Max 5 Prefs folder. AOK now.

blank patch screens, blank preference screens ?
