Windows XP SP1 and SharePoint 2003 Hotfix Trouble

SharePoint users at my customers' site were complaining the other day that any Office 2003 documents would not load from a SharePoint 2003 site through IE 6.  In fact IE would just freeze up and then have to be closed with extreme force.  All other non office documents were fine.

The clients were Windows XP SP1 and not all of them were having the problem.  Comparing clients that did work with ones that crashed showed that there was an inconsistency with the hot-fixes that had been applied.  Clients with the problem did not have KB925486, a security patch for IE 6, installed.  We installed it, rebooted and the problem as gone.  This patch was released a while ago but subsequent patches had caused the problem.
