My deathknights don'

Hello, I finally managed to get my deathknights to level 85 yesterday, and I was super excited since the last level took me 14 hours. >.< Anywho I have been boxing for a year and have played shamans up to 1960 rating on bloodlust. The reason I come running to the forum today is because yesterday I tried to work my deathknights on my laptop, (they work fine on my desktop), and I encountered some problems.

I set up my macros like I did on my desktop, the ones from Mosg2's deathknight thread (as well as the ones from that awesome video). But I ran into a problem. Whenever I press my DPS key, it does IWT (once I beleive), and then it goes through my DPS rotation. When I release th key and dont press it for another second, the key and its purpose work fine, my deathknights circle around the target bashing it and using the howling blast, frost strike, exc exc. Yet when I spam my key they go at the target once and then make LARGE circles around the target, when I say large I mean they go at the target then keep moving to the left at a maybe 5 degree angle, which leads them to go crashing into a wall.

Sadly when I tried to do arena last night I won three, the keys didn't really worked by the teams were undergeared. Yet I lost 5 teams mostly because of my macro which crapped out.

So today I went ahead and cleared my whole isboxer profile and will be starting fresh when I get home from work. I was just wondering if anyone else in the community has faced (and perhaps tackled) this problem headon? Thank you for your time and once more thanks to Mosg2 who gave birth to my new "mains"! =D
