Well, actually I don't see any problems disabling the splash screen at all. Comodo Firewall still _has_ this issue with Java Webstart. I was told you can set it into some autolearning mode to make it work with java, but I don't have the resources to try this at the moment (as I got my grade for my thesis today and will be quite drunk the next few days
).
If you get this to work, please make sure you post your solution on this forum as well....
