Hm. Strange, works for me. You run it from the xterm, right? (Oh, and you must not run as root.) Does it help to use run-standalone.sh, like "run-standalone.sh callerid +45..."?

It staying up is intentional, since I wouldn't want the banner to disappear while fumbling to get the phone out of my pocket or whatever. Even if the caller hangs up, I want it to stay up so I can read it afterwards.

So, like with many other Hildon questions, you must tap on it or above it to make it go away. I've considered adding a dbus listener so it would go away on its own if you click answer or reject, but don't know when that'll happen.
