Description Matthew Truch 2003-09-25 03:47:01 UTC 
Version:           0.92 (using KDE KDE 3.1)
Installed from:    RedHat RPMs

When the mouse is over a plot, the lower right of the kst window shows the current mouse location.  However, when you are looking at live data, and the data is scrolling by, this location (indicated at the lower right) does not change (until the mouse has been moved).  The data should be updated as the data scrolls by even if the mouse is not moved.
Comment 1 George Staikos 2003-09-25 11:40:35 UTC 
Working on the patch for this now.

This seems to update the mouse properly.
