FYI, I noticed it ran on my newer PC today which it didn't a day or two ago (The error message I'd get would be because of the version of Java installed). So perhaps it may be a java issue more then an E-trade programmer issue (wonder if you could have configured it to use the older version?)
I recall a while back in earlier days when working with some Java each time their would be an upgrade some of my programs would behave differently.
I haven't figure out E-trade pro yet to use it much so I didn't have any layouts set up. I am not an active trader so the basics are more then enough for me at this stage :)
