Win7 has a higher requirement for system resources than XP. This is not
generally a bad thing as it is doing a lot more but still...

How much RAM do you have installed.

Open your Task Manager/Performance and see what your load is.

Also, the PlanePlotter website says that it runs on XP -- are you running
something else that could load the system to the point where Win7 stutters?
