User-Agent: Mozilla/5.0 (X11; U; Linux i386; en-US; rv:1.4a) Gecko/20030323 Build Identifier: Mozilla/5.0 (X11; U; Linux i386; en-US; rv:1.4a) Gecko/20030323 In any page (the larger the page, the more noticable this is), when the browser window is resized, the section of the content that is displayed is changed. Of course, if you were to resize the window vertically (to make it half as tall, for instance) only half of what was formerly visible will be visible now, but this is not what I mean. When the window is resized horizontally, the place, or position, that you are at in the content changes. I noticied this while reading a long story in my browser. When I made my browser window narrower to see something behind it, I suddenly found that my place in the story was completely different. The best way to explain this is with an example. Please follow the steps to reproduce the problem below. Reproducible: Always Steps to Reproduce: 1. Make your browser window as wide as possible. 2. Go to http://outroad.org/mozillaWindowResizeBug.html 3. Scroll down until paragraph 500 is at the top of the browser window (about half-way down) 4. Resize your window horizontally so that it only takes up half of your desktop (make it half as wide) 5. You will now find that you are somewhere else in the document, probably around paragraph 350, depending on how large your desktop is and how much you narrowed the window, I would guess. Actual Results: The portion of the content that is displayed is not paragraph 500, but somewhere around paragraph 350. Expected Results: Whatever portion of the content that was at the top of the window before the resize (in this case, paragraph 500) should be at the top of the window when the user has finished resizing, they may continue reading where they left off without scrolling to find their place again.
I see it too on XP, Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4a) Gecko/20030323 What seems to be happening is that it is keeping the top line in the window the same *number* of lines from the top of the page which, because of the line wrapping, is not as far down the page. Not that I have any intention of counting the lines in that page to prove it ;-) The same thing happens if you change the text size from the View menu.
Suggested behavior: - At the beginning of re-sizing, note a point in the document corresponding to some point or line in the rendering area (e.g., the top of the pane, or wherever HTML anchors are placed for "...#anchor" URLs). - While re-sizing, continually adjust the vertical scrolling position so that the noted point in the document is displayed at the top of the screen. (That is, keep track of how far down the document is scrolled via the content, not just the number of pixels scrolled.)
