Description Andrew Walker 2008-05-09 17:00:36 UTC 
Version:           1.4.0 (using KDE 3.5.8)
Installed from:    Compiled From Sources
OS:                Linux

PROBLEM:

A KstBasicPlugin will update every time even when its inputs have not been changed.

STEPS TO REPRODUCE:

Start Kst
Create an auto-correlation with the inputs being two large and non-changing vectors
Create a curve from the auto-correlation output vectors

RESULTS:
Kst consumes a lot of CPU time

EXPECTED RESULTS:
Ksy updates the plugin only once and does not consume a lot of CPU time
