Yes, that is interesting....I see
Which is a copy/snapshot of when I copied the folder over from machine #1. The URL I use is machine #2. And when I use the startup.bat from the copied folder, it starts up like this.
I'm using FireFox 35.0.1 (set as my default) in case that makes a difference. Also, sometimes I fire up the startup.bat, the node.js window pops up....I wait a few. then if the browser window doesn't start the session clean (or at all) I close a tab if partially started, close the node.js window, and use the startup.bat again. the it usually starts. Not ideal, but whatever works.
Update 9:15 AM AK-time: I just renamed my WAB folder on machine #2, then did another complete copy of my WAB folder from #1 (so I had a frech snapshot, and could work on #2 while machine #1 (my prime dev machine and the one listed in the AGOL appID) is busy doing other stuff. I then used the startup.bat in this copied folder, and it fired up just fine. The address firefox still shows it as my #2 machine. So, I can use both machines....but will need to figure out a good way to keep them in sync. -ras
