When I double-clicked Internet Explorer 7 on Monday, it didn't go to my home page. Instead it created two windows, then cancelled the navigation. It asked if I wanted to download an unknown 2.64K file called navcancl from ieFrame.dll instead. (By the way, it's very easy to misread the filename as navcand.) Clearly I did not, but either way, it stopped IE7 from running. Jack Schofield
This is due to an error in the operation of the anti-phishing filter, and it has been introduced by Microsoft along with the May 2007 Cumulative Security Update for Internet Explorer (MS07-027). It has affected an unknown number of Windows XP, Server 2003 and Vista users. Microsoft has now published two workarounds in article 937409 in its Knowledge Base. If you are running XP, ignore the first sets of instructions which apply to Vista -- in other words, start half way down either Method 1 or Method 2. Another workaround is to turn off the phishing filter.
Note: I never write my own questions. In this case, I did suffer from the problem, and had to solve it. I guessed that a lot of other people would be affected, that several readers would write in about it, and that I'd be able to swap one of their queries for mine at the last minute. As you can see, it didn't happen.....
