Version: 1.2.1 (using KDE KDE 3.5.0) Installed from: Compiled From Sources OS: Linux PROBLEM: Both the x-axis and y-axis can in some circumstances display neither tick marks or numbers. STEPS TO REPRODUCE: Start Kst Create a plot Move the cursor within the plot Hold down the SHIFT and '>' keys to zoom out RESULTS: When the axes eventually reach 10^-308 and 10^308 they will then display neither numbers nor tick marks. EXPECTED RESULTS: When the axes eventually reach 10^-308 and 10^308 they will stop there and no further zooming out will be possible
