if I scroll halfway down a web page in Safari, switch to another tab, then switch back to the first tab, Safari shows me the page still scrolled down to where I had it. OTOH, if I switch documents in DevonThink, it opens documents back up at the top instead of where I was scrolled to. Is there a setting or something or is that just how it works with no other option? Thanks.
What type of documents are you working with? If I scroll down a page in a document in DEVONthink, switch to another tab, then switch back to the first tab, DEVONthink remembers the position in the document.
