Dreamweaver High CPU

Hey,

I've been running Dreamweaver CS3, and have been noticing extremely high CPU
usage, which makes working on a laptop a real pain, as it gets very hot, and
the fans are on loud and constantly.

I get this CPU activity even when Dreamweaver is supposedly idle, I've open
the application, and nothing more. Closing the application immediately fixes
the problem, and when Dreamweaver is running the machine isn't running
noticeably slower, therefore it must just be picking up the idle CPU threads.

But why is it doing this, ive looked into this, and the last activity for the
offending process in the call stack is this...
ntoskrnl.exe!KiDispatchInterrupt+0x7f

Dont know if that has anything to do with it.

Any ideas I've always like Dreamweaver but this new version is making me want
to down grade.
