[Javascript] "Multiple" Select controls and popup objects.

[Peter Brunone]

Hi Matt,

    I've only worked with the popup object a little, so I don't know
much about it -- other than it can be very temperamental -- but if you
don't mind a shameless plug, I recommend checking out EasyListBox (
http://easylistbox.com ) to deal with the annoyances of <select>
elements in IE (and someday in Mozilla as well).

Cheers,

Peter Brunone

Hi,

This is a win/ie5.5+ issue only so anyone offended by that can switch
off now if they like ;)

I have a menu system in my app which lives inside a popup object [i.e.
window.createPopup()] which has been behaving just fine for months.
However today I noticed an odd quirk which I can't explain, let alone
work around.

When the popup menu appears it covers a set of html frames which can
each contain a variety of html controls.  When one of the controls
covered by the popup is a <select multiple="true"> control then when
moving the mouse over the popup I can see the multiple select underneath
flickering, as if the popup is disapearing then being redrawn very very
quickly.  It seems to be when the mouse moves over the borders of table
cells on the popup.  There's no onMouseMove, onMouseOver or onMouseOut
events defined anywhere and there's no problem with any other kind of
control (even <select> controls which aren't "multiple").

Anyone hazard any ideas? It the moment I'm putting it down to (yet
another) unspecific vagary of how IE handles (or not) select controls.
This is rapidly becoming my favourite pet hate... grrr.

Cheers,

Matt
