There is a problem with textarea, when you want to select contents of it and drag mouse from start down the page. Here is what happens 1. Open page ( above) 2. There is a TEXTAREA with sample XSLT in it.Use the mouse to mark the text (starting from top, draging down the page) 3. Page starts to move because textarea is taller than screen. Page does not stop until bottom of page is reached(textarea is already offscreen) 4. Release mouse 5. Right now you lost focus. It is imposible to move the page and so on (scrolltab is not working) Mozilla's window must be small so that TEXTAREA moves offscreen during draging the mouse
Confirming (didn't find dupes although they might exist). I see this on trunk build 2002081604 on WinXP. Looks like it doesn't stop selecting (notice that I've released the mouse button) after the textarea has gone off-screen.
