At least this one page will not work properly. The page consists of two frames. Actions in the left hand frame updates the right. The HTML of both frames is created entirely by JavaScript. The left frame consists of a table that uses the onmouseover (highlight the cell), onmouseout (restore cell to normal appearance, and onclick (update right hand frame) events in the cells. In Communicator 4.7, everything works fine, but in M11, it all goes to hell. Clicking on a cell does not update the right hand frame. In addition, moving the mouse over the table can leave both the top cell and one other cell highlighted. Only one cell at a time should ever be highlighted. In addition, M11 has made the width of the left hand frame much too big. Visually the frame is layed out ok, but it has a horizontal scroll bar that scrolls about a third of the frames width and that is not present in 4.7. The URL is an ad so it may not be around for too long. I have copied the code of the left hand frame and placed it at: http://www.wenet.net/~stephe/xfer/mozbug1/jshell.html

The extra scrollbar is due to bug 14827. I'll look in to onmouseout and onclick not working as they are supposed to.

Reviewing this bug in the post M12 world, I can see that Mozilla is behaving better but is still not working correctly. I can no longer duplicate the problem of the multiple highlighted cells in the left frame due to onmouseover and onmouseout. Mozilla now partially updates the right hand frame, and the extra scroll bar problem remains. So, the previous bug description is obsolete. A new description follows: In the attached testcase, FrameWrite.tar.gz, when you click on one of the links in the left hand frame, a JavaScript function is run that writes html into the right hand frame. The right frame should consist of a .gif image followed by some text with another .gif image at the bottom. In Mozilla, I only see the text. In Communicator 4.7, I see both images and text.

A couple of things I forgot to mention: The html that JavaScript code creates has tables. If I change the code to not use tables, Mozilla can load the html in the right hand frame ok. If I load the testcase in Communicator 4.7 and click on a link in the left frame and then save the right frame as html, Mozilla can load the saved right frame tables and all.

I'm able to reproduce this bug. Perhaps the base URL for the image isn't set correctly and that's why it's not loading? Looking in to it.

Yep, that seems to be the problem, if I give an absolute URL for the image instead of a relative URL, the image is displayed...

This relates to some work Vidur did with document.open (nsHTMLDocument) setting the base URL to be that of the calling script. In this case, we are calling document.clear not document.open. This calls nsHTMLDocument::Clear() which in turn calls nsHTMLDocument::Open(), but there are two nsHTMLDocument::Open's, and this is the wrong one. (for non-script cases) Thus the base URL gets set to about:blank instead of the calling script's base URL as is needed here to load the image. Attaching a reduced test case.

Fixed the document.clear() issue on 1/2/2000. Did this fix the original problem reported? Pollmann thinks so, so I'm closing the bug.
