Smart guides not working
Hello! I have read previous discussions on issues when the smart guides options gets grayed out due to accidental selection of "snap to document grid". I am wondering if there is a possibility for other commands to deactivate my smart guide. I have retrieved an idml layout file from work and it does not work for that file. My smart guides are working for my other indd documents.
I am also curious what the green boxes grids are? Thanks in advance to any help!
