Help! v4 froze!

I’m building a GUI, and I’m almost done. But the v4 surface froze up. The patch itself in the ex9 render is running just fine. I cant move any modules, and I can’t even scroll. What is wrong? Is the some sort of lock I accidentally put on my patch?

Ctrl+e can lock/unlock patch.
When a patch is locked you can see a # in the title bar.
