Hunters can't cast spells

So I am not sure if this is IsBoxer related, or if Blizzard is doing something wierd but I am leveling a new trinity comp and when I am in dungeons, after a while my hunters are unable to cast any skills or use items, they can't even auto attack. This will persist until I either relog or exit the dungeon.

I already made a ticket with Blizzard but obviously they say they don't see anything wrong and as soon as you drop the term multiboxing they instantly stop giving support.

At first I thought it was addon related so I disabled every addon but IsBoxer but the problem still persists. I even did an interface reset (delete WTF/Cache/Interface) but that made no difference.

The funny thing is, this only happens on my hunters, my DK (tank) and druid are fine.

Has anyone ever experienced anything like this before?

Are your hunters just passing a keystroke or do you have your dps macro inside ISBoxer? If it's the macro in ISBoxer it probably is hitting a step that it can't get past. I had that happen a bunch as I was getting my macros working.

No I only have keypresses in isboxer, the actual rotations are in game.

I also figured out that this is Blizzard related. I ran retail wow without any multiboxing software and it also happened. Opened a new ticket with Blizzard so hopefully they can find something out.
