Atlantis no longer always saves my cursor location in .rtf files. Sometimes it does, and sometimes it doesn't. At least it doesn't always restore the document position when I open up. BTW, when it doesn't work right it takes me to the last page of the document, not the first.
I can reproduce this glitch when a document contains footnotes or endnotes, and the caret is within a note text when I save it. This glitch will be fixed in any next release/build of Atlantis. Does your document contain footnotes or endnotes?
