Version: 1.2.1 (using KDE 4.3.2) OS: Linux Installed from: Archlinux Packages Plot a random function, anything will do. Then zoom in to some arbitrary point of the function, again and again. When you zoom in far enough, KMPlot will hang. I came across bug 133640, but it's quite an old bug and is about the KDE3 version of KMPlot. Using 64bit packages of the KDEmod repository of Arch Linux.
