Description Matthew Truch 2003-11-12 01:44:33 UTC 
Version:           0.94 (using KDE KDE 3.1)
Installed from:    Unspecified Linux

If you choose a valid (according to the format file) vector, but that vector doesn't exist on disk (ie you didn't copy the whole data set from another location), kst uses up 'mucho' CPU.  

How to reproduce:  Within a dirfile, delete one of the elements.
open kst, and create a curve which uses the deleted element (either directly, or a derived vector that deponds on it)

Expected Behavior: kst won't use up much CPU, and just ignores the file (or pops up a dialog box to complain, etc).

Yes this seems to be the case

Can you update from CVS and try what's there?  I fixed one bug, but I'm not sure if the cpu usage I see is abnormally high now or not.  I profiled it and I see nothing out of the ordinary right now.  It is afterall drawing a graph with labels so there will be some cpu usage even though there is no real data.

as far as I know, it's fixed
