           Summary: Unnecessary updates occur in plugins
           Product: kst
           Version: 1.4.0
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: arwalker sumusltd com


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
