Yes, OZ 3.5.1. This is really the first OZ I've used, and it's breathed so much life into my li'l 5000D that I'm willing to work around the pauses, but it IS extremely annoying.
Zen, often it is non-responsive for up to 10 seconds and DOES come back... other times it never seems to come back at all, and after about 30 seconds to a minute I lose patience and reboot. It appears to be buffering events, because I will occasionally, say, turn it on with Opie-Reader paused, read the page, and scroll down... nothing, nothing, nothing, then many seconds later the buffered events come back and I whip through a few pages instantly.
Workable, but extremely annoying.
