first time 5-boxing

[tldr]

I'm in Deadmines with this group a second time and am finding entertaining little things to be wacky. I had set up symlinks between my accounts to make things easier for Altoholic, but the end result has been:
1) my 2nd account, which had been set up to use the same set of directories as the first, had its macros changed around to match the first. So, my focus button was gone entirely and my arcane shot spam macro had been replaced with /cheer. As a result my first fight involved 3 hunters shooting and one going WOOHOO every few seconds.

2) When I fixed the macro on the 2nd account, I had opened up the macro window for the 3rd account to copy its contents back (I'm going to have to learn better macro management soon, methinks). But I managed to leave it open. So the second fight initially involved replacing the arcane shot macro on toon 3 with 11111111111111111111111111111111 but the macro window got closed at some point so now I have three hunters shooting and one saying 1111111111111111111111111111 over and over. I nearly did the macro thing again just now, and to add insult to injury, I found that I had switched off key broadcasting before the next fight.

Regarding earlier replies, thanks :-). Khatovar in particular has been quite helpful in filling in the gaps in my knowledge. I actually did, for the window resize/move exactly as you describe in your response. That example was where I had started from. In fact, I've used it several times already this evening.

The dungeon finder is pretty much what I expected, but it'd be nice if I had the option, with a full party, to run it anyway.

Part of this is me learning to play some of these classes. My main has always been a hunter - I've never leveled a pally past 25 and that was 5 years ago. Lots of learning-by-doing.
