Hi Jono,
[yesterday:]
Well, here IE6 under Win98SE, and flashing like thunder...
Cache was empty enough. - It's not the page loading flash or refreshing
flash, but it is performing every time when hovering in and out the logo...
First impression: looks like kinda peekaboo.
But went to my IE-settings, and indeed (as Holly said): that's it!
Only strange, that normally I don't remark this kind of flickering. I
should say it should happen on visiting other webpages too [1], but why not?
So somehow there must be a connection between the code of your page and
the IE-settings...
Back to html. - I saw:
<meta http-equiv="Pragma" content="no-cache" />
* "Description: Causes the browsers to not locally cache documents."
http://www.html-reference.com/META_httpequiv_pragma.htm
Aha! Should that ..? - No problem for FF anyway, but turned it off in a
testpage. - No, it wasn't that...
[time to sleep]
[today, after some heavy dreams about IE and thunderflashes:]
Maybe...
Yes! Almost too simple, see testpage
<http://home.tiscali.nl/developerscorner/css-discuss/test-ie-flicker-1.htm>.
:-)
Evaluation:
Hé, if you go from testpage 2 back to testpage 1 with the "back" button
on the page (in fact: reload page 1), the flickering is starting again
on page 1. - But if you go back with the IE back button in the menu bar,
the flashing in page 1 is over, like I did imagine it was flashing...
Maybe it is mr. FOUC [2] or one of his family members. - But as the
solution is working, it's more up to the IE people to find the reason
and to repair that, than a task for us: we just want to make websites,
not to develop browsers! ;-)
Good luck,
francky

Also in the case of your reporter. If it only was a cache / IE-settings
problem of your reporter's machine, then the flickering should be a
"common behaviour" for your reporter, and there was no reason for a
special alarm to you... - If not a general issue for people with these
IE-setting, then probably it is the page, I was thinking.
