Bug 59989

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8) Gecko/20020206

Description of problem:
When trying to use mozilla with my internet bank, I get an error message
whenever I move the mouse over the menues.  Starting the javascript window, it
gives an error message saying "document.layers has no properties", referring to
line 1217 of
http://demo.skandiabanken.se/SKBSecure/control.asp?stamp=2002%2D02%2D18+12%3A35%3A35

Version-Release number of selected component
This happens with all of the mozilla RPMs I've tried, up to and including
0.9.8-2 from rawhide.

How reproducible:
Always

Steps to Reproduce:
1.Point mozilla at http://demo.skandiabanken.se/SKBSecure/index.asp
2.Click on "Logga in" down the bottom of the page.  (Means "login".)
3.Move the mouse over the menues at the top of the resulting page.

Actual Results:  An error message window saying

  Tyvdrr uppstod ett tillfdlligt fel med toppmenyn.
  Prova att ladda om sidan.

Don't get scared by the Swedish!  :-)  It's a message from a function
"errHandler" which has been assigned to the variable(?) window.onerror in the
beginning of the script.  What the text says is "Unfortunately there was a
temporary error in the top menu.  Try reloading the page." And the javascript
window adds an error as described above. (Of course, actually reloading the page
makes no difference.)

Expected Results:  I would like to select entries in the menu.

Additional info:

This works in old netscape 4.77.

I've never learned javascript.  "document.layers" appears to be used as an array
of some kind.  I don't see anything which resembles a declaration.  But maybe
this is something which is assumed to be predefined, I can't say.

I don't know if this is an error in mozilla which I should report upstream, an
error in the script which I should report downstream (to the bank), or an error
in Red Hats packaging.
