Messages selected with the mouse are displayed instantly. Reproducible: Always Steps to Reproduce: 1. Go to a folder with multiple messages 2. Select the first message 3. Press the down arrow key to select the next message Actual Results: The preview pane will take a few moments to update and display the currently selected message. Expected Results: The preview pane should update instantly, as it does when messages are selected with the mouse. Pressing the delete key to delete a message updates the preview pane instantly. It only seems to be the arrow keys and page up/down keys that are affected. This behaviour might be by design, to allow fast movement of the selection indicator via the keyboard without the preview pane slowing things down. However, at the very least there should be a parameter in about:config to set the amount of delay, or disable it. The current delay severly slows down navigation and operation of Thunderbird via the keyboard.
This problem can be fixed by installing the userChrome add-on, then adding the following to userChrome.js: document.getElementById("threadTree") .setAttribute("_selectDelay", "0") However, there should still, IMHO, be an about:config value. Plus, the default delay of 500ms is far too high. 100ms should be enough, 200 at the most. 100ms works well on an old 800MHz Compaq laptop with Windows 2000 and 128MB RAM.
version 3.0a1pre (2008040302) Windows XP SP2 It can be reproduced. Clicking and selecting with mouse just don't produce the same effects, since keyboard-commanded switch is delayed.
