Version: (using KDE 4.3.1) Compiler: GCC 4.4.1 OS: Linux Installed from: Unlisted Binary Package The network monitor widget starts to plot the network speed in negative after trasferring a large amount of data. I suspect it happens as soon the total amount of data transfered goes beyond 4GB, most likely due to the use of 32-bit integers, and these integers get overflowed when transfered data reaches 4GB. Qt: qt 4.5.2 KDE: 4.3.1 on ArchLinux i686 - Kernel 2.6.30.5
