Are There Issues With 64bit Win 7?

The reason I'm asking is because I've noticed a few little problems. I've re-organised my music libray, and as I was doing it, I was playing a few tracks, and the program seemed to encounter big problems...
Originally, I ran Cross DJ 1.7 on a low-spec laptop, and it ran fine, no matter what I did. Now I've got a high-end laptop I seem to be getting a few problems... strange considering that my new laptop is much more powerful than my old one...
Every little action seems to lock the display at the top, and disables the scrolling of the tracklist... even though the music keeps playing just fine...
with a fast quad core laptop, with 6gb ram, I didn't expect this sort of problem!
