Office Patch
As I'm sitting at my desk the other, showing a couple of co-workers our patch management process, I tried to open a document from our Sharepoint site: IE Crash! That was weird. Let's try that again: same result. Reboot, open IE, go to SharePoint, click on document, crash. Must be that new McAfee that was pushed to my desktop. Disable McAfee, repeat process, crash.
Time to do some searching. Lo and behold, it turns out that this is a known issue if you have components from both Office 2003 and Office 2007 loaded: Description of the 2007 Office hotfix package: June 17, 2007. Everything works great after the patch and a reboot. The issue just now reared its ugly head because I just loaded Project 2003 the other day to do some project planning.
