I have been working on a model with no issues until now. I added a label, then decided I wanted 3D text there instead, so pressed Ctrl+Z to undo it. When I selected the 3D Text icon, the entire window went inactive.
If I click on the window now, the floating toolboxes appear but I can’t do anything with them. If I click on them or anywhere in the main window, including toolbars, menus, or the title bar, it chimes at me. The title bar is white instead of the normal blue-grey, indicating an inactive window.
Anyone have any ideas?
