OS: Linux I have two images in a web page and have a JavaScript function to hide and show them via CSS: document.getElementById(...).styles.display='none' Hiding the first one is fine. Then hiding the second one and then asking for the width of the second image will crash Konqueror. I've tried this on i686 Linux machines. One of them was SuSE 9.0/KDE 3.3.2 (crash handler report below is from this machine), the other was RedHat 8.0/KDE 3.2.3. I don't have a newer version of KDE.
