I'm cross-posting this from the deviantART forums and I've decided to post this here to see if you can help solve the Internet Explorer issue involving the USP10.DLL file. I have a problem with running Internet Explorer 9 under Windows Vista x64 and it has to do with the USP10.DLL (Uniscribe) file. Every time I try to view someone's Twitter's account using Internet Explorer 9, the browser crashes! Here's the error from the Event Viewer that I received: The Event ID is 1000. I'm wondering if this error is reproduced with Internet Explorer 9 under Windows 7 or Windows Server 2008. Could this issue also have to do with a defective security update KB2957509 that was released earlier this month? I should scan this computer for malware to see if this might be the cause or not? Just curious.
