I've searched thru the manual and this forum but cannot find how to have the reader ask me if I really want to quit. Sometime, I might have 3 or 4 or more docs open and switch between the tabs comparing them. I every so often click the X to close the app instead of the X to close a tab, and then have to reopen all the docs and try to get back to wher I was. Put it down as a "Senior" thing, but it has gotten rather irritating It would be nice to have a "fail-safe" mech built in to prevent me from closing all rather than 1 tab. Any help would be appreciated.
