Hi Steve,
Yes thanks, I don't think I was clear in what I wrote. I knew that they could be turned back on, but why did I open InDesign this morning to find my workspace/preferences different than how I left them on Friday?
And I know it isn't a case of my mistakenly turning off the frame edges, because the operator that sits next to me had the exact same thing happen to her copy of InDesign this morning also.
I understand the requirement to update things, but it really does feel as though I'm using software that is still in testing.
