I love the smart guides and use them all the time... unfortunately my smart guides have been turning off (I'm either inadvertently doing something, or this is a glitch or something going on) but after using smart guides on a document it all of sudden stops working. The only way I've been able to negotiate around this problem is by opening a new document and just copying my old materials in there and moving forward like that. That's a pain and and also doesn't explain what's going on!!!
When I go View> Grids & Guides ... smart guides is selected but the option is grayed out and I can't change it even if I want to. I'm really not sure what's going on here. Using CS6
Any help is much appreciated!!!!
