Actually, I tried it on the iPad first, and when it wouldn't connect, I then tried on the Macbook Pro, since it was also connected via wireless it seemed the best way to test any connectivity issues with the laptop running XP. It connected immediately, as did my iPhone. I also tested it from Safari on my iMac without issues. After I sent this last night, I installed the CRJ on my iMac, and all my devices can display the CDU when XP is running on my iMac, but it still doesn't work on the iPad. I don't see anything in the network or browser configuration on the iPad that might explain the inability to connect, so I have no idea what's causing the connectivity issue. It's running the latest iOS release, and I even actually rebooted it to see if that made any difference, but nothing so far. Before posting this, I thought I'd try a different browser on my iPad, so I downloaded Terra, and it works with it. I have no idea what's going on with Safari on my iPad, but I'll happily use a different browser if it will work. I'll try it out later today and see how it does.
