I'm not sure if it's the latest update or not, but multi-line text blocks on Windows/Chrome are not available any longer either in schematic or PCB layout. I've tried Enter and Shift Enter and Alt Enter and using /n or \n ... none work.  I can, however, write the text out in NOTEPAD and copy and paste it into a text block. But this seems a poor work around. Let me know if a fix is in the works. Thanks
