Re: Dialogs, opacity, and IE6 security
- Still haven't been able to precisely locate the source of this
problem, but i think it is specific to our internal environment. For
the benefit of any others who run into similar problems with opacity
in IE, i'll post these final notes.
I believe the issue was in the interaction of a recent IE6 security
update, our enterprise security settings (which are quite tight), and
the configuration of our Web servers. I believe that an even more
recent IE6/Windows XP update -- perhaps released 12/18/2006 or earlier
-- resolved the problem. It may also have been resolved by some
fiddling done with our IE security settings for intranet "trusted"
sites. There may be some relationship to DirectX (used to implement
opacity in IE).
I also believe that this issue was related to a pernicious security
warning we received with some implementations of Overlay, even with
the most recent version of the library. When we began having trouble
with opacity, we also began getting the "there are secure and insecure
items on this page" warning when hiding and destroying a customized
Overlay (containing Calendar and Menu objects) we are using. When the
opacity issue disappeared, it appears the security warning did as well.
I hope this is unique to us, 'cause it's been a real pain.
