Confirmed, although it doesn't require loading a .pp2 file.<br><br>Just to fill in more details that I've observed:<br><br>If you change to a previous route via the Route Changes box then exit PP, PP crashes. If you change to a previous route, then back to the "latest" route (at the top of the list), then exit, PP doesn't crash.<br><br>On my NT box, the runtime errors do not appear. The good doctor simply puts PP out of it's misery. Win98 at home does show the runtime errors during the crash, which continuously re-appear until the PingPlotter.exe process is killed manually.<br><br>Jason Brunette<br><br><br>
