Microsoft's Patch Tuesday last week meant a sigh of relief for sysadmins dreading the nasty Internet Explorer vulnerability discovered last month, but any relief was short-lived as the round of patches has apparently led to a plague of bugs and incompatibilities. Last week's patches are causing "causing system hangs, Windows crashes and the appearance of strange dialog boxes" and interfering with apps from Google, HP, and even Microsoft's own Windows Media Player. One company is also saying that the new Internet Explorer plugin behavior resulting from Microsoft's patent dispute with Eolas is causing problems for enterprise customers, who are having to click several times to use ActiveX controls. As usual, none of these problems will be fixed until the second Tuesday of next month.
