--- Comment #13 from Jacek Caban jacek@codeweavers.com 2008-11-25 06:54:54 --- The proper fix will be a lot of work (that I was planning to do soon anyway). Steam sets scroll height in callbacks called from navigate_complete. We call these callbacks too early for http pages because of hacks in MSHTML (so we don't have proper progress notifications in shdocvw). Steam gets 0 height because the page is not yet loaded.
