I have noticed a certain issue when running Scan Tool on my laptop.

During a logging session, the highlighted cell will not match the current operationing conditions. For example: I will rev the motor. The highlighted cell will not change position for a while. Then it will mirror what just happened 3-5 seconds too late and FINALLY settle back down at the cell I am idling at.

I believe that might be a huge cause for error!

Could this be a hardware issue? Or maybe a software issue caused by laggy vista??

This is my computer specs

Vista Home Premium bd# 6000
2 gig ram
1.8 ghz Turion 64 2xcore
10 gigs devoted to paging file

Interestingly my Scan tool says build version 515 and 644 on the about screen.
