Build: 2000030516, also 2000030909 Win98. See the url. Let the animation bring the panel to the screen. See that there is nothing in the blue area. Click the mouse in the center of the blue area.. see that there is a form. The form was created in HTML, with div and style...visibility:hidden. Then the visibility was changed to visible. And nothing happens until you click or cause some repaint. For example, try again but now.. alternate windows with alt+tab and alt+tab again...

This is a dup of bug 13047. Same testcase: a DIV with style="visibility:hidden;" and a script that changes the visibility. FYI, there is a workaround. The reporter wrote in 13047: If I leave out "visiblity:hidden;" I can freely switch the visibility between "hidden" and "visible". *** This bug has been marked as a duplicate of 13047 ***

This bug is in fact invalid. The width and height should not have been applied to the <form> element but to its parent, the "areaform" <div> element. See the fixed page that I'm going to attach. - I understand it was a bit confusing because many workarounds were possible. - I file a related problem under bug 41188

Verified duplicate.
