if you are having problems with your entire internet connection dropping for some unknown reason while running ouka or after having run ouka, update to latest version just released (560b - links in GhostShip's post above mine)
I was having probs all through the month of August that were so bad my isp replaced my modem/router because it kept resetting itself...which didn't help any. It still kept resetting. I didn't think it was Ouka that was causing the trouble because it still happened even when Ouka wasn't running.
But as soon as I updated Ouka, my probs disappeared like magic and my connection is fine now.
Nobby was right...last version was really bad. Some major bug in it.
So if you are having any funny connection probs, try this new version out.
