I have built a site where content is loaded into an iframe. (http://www.ecm.qc.ca
Everything is OK in other browsers but intermittently, in Explorer 7, when clicking a new link to load new content into the iframe, the old content sometimes remains, so you have 2 or more pages of text superimposed over each other.
It makes the text illegible and looks very strange. This seems very straightforward and should work - I mean, elementary browsing (click link, it appears) and I've never seen this before.
is this a bug in IE7? or is there something I can do to eliminate this?
