UI Issue/Bug

I have an issue with my UI see attached photo basically every tab in that area is not clickable. I cannot expand or close my insert, sends tabs. No idea how this happened, anyone has this problem before? Hope I can get a fix soon.

Things like that are usually caused by corrupt preferences.
Back them up first, then have cubase generate fresh ones

or, as this is probably due to a corrupt default.xml file in the preferences, just rename this so cubase will generate just this file anew (so you won’t lose any other settings)

It is ok now, all I did was restart the computer… Should I still initialize the preferences?

No, trashing prefs is always a last resort.
I thought your problem was more permanent
Good it’s solved.

OP, was that user name really necessary?
