Anyone know what caused this d/c?

I mean the type of d/c where your MS freezes and moves to the corner of the screen, before quickly kicking you to the login screen.

 Background: Zak d/c

So, for quite a while, my guildies and I have been getting what we call the "Zak d/c". About 2-5 minutes after we finish a Zakum run, while we are signing up for the second run or just sitting around talking afterward, some of the people who went will d/c without warning.

First, the screen freezes and offsets itself to the corner of the screen (can't remember which corner, I think it's top left). That only lasts for about a second, then you get kicked to the login screen, or sometimes, Maple closes itself.

We think it's related to the order you sign up for the Zakum squad, because it seems to happen most to the people who sign up in the first 2-3 slots, but that isn't a guaranteed rule for who will d/c.

Anyway, the Zak d/c itself doesn't bother me a lot, since it doesn't affect bossing any more than having to hold the squad for a few minutes while people log back in and walk/get doored back to the altar.

I got a d/c that looked exactly the same the other night, and it was a lot more serious. I got it maybe a minute after we had summoned and killed the pre-bosses for CWKPQ, just when we were about to summon the bosses. (So I missed the boss fight.) I didn't sign up early; in fact, I looked and I was about #13 on the list. As far as I know, I'm the only one who d/ced this way. I wasn't lagging right before; I received chats maybe a second before I d/ced, and was moving, buffing, and chatting normally.

The only thing I hadn't done in CWKPQ before was that I happened to be the one to get all the mage sigils, and I got and placed the staff. So did me being on the ball before the bosses actually hurt me?

I use XP and I have plenty of RAM. No other programs were running besides Maple, and at least the Zak d/c happens to virtually everyone I've ran with. This is the first time I've had/heard of a similar d/c in CWKPQ, though.

I've had this a lot in CPQ a while ago. Like 1 or 2 years back before pirates.

Yeah, now that I recall, I had it happen to me a few times in CPQ. But why did that stop, and this Zak/now CWKPQ issue continue?
