Version: 0.3.34 (using 4.3.98 (KDE 4.3.98 (KDE 4.4 RC3)), Arch Linux) Compiler: gcc OS: Linux (i686) release 2.6.32-ARCH It's an very strange bug. It only happens in the bottom input field of Google's search result page, the upper one is normal. When you select a piece of text by mouse from right to left (selection from left to right is normal), if your cursor is beyond the input tab while you are still holding your left button, the selection would be cancelled.
it's a WebKit bug, as it also happens in arora. Reported it upstream: https://bugs.webkit.org/show_bug.cgi?id=34648
