This evening while uninstalling Microsoft Office 2007 Beta 2 I got this alert message:
Erm… which applications? Install?!
Later on I was pulling out my hair (what there is left of it) trying to work out why my Mozilla Firefox document icons had disappeared from all .html and .htm files.
Thanks to my friend James he found the solution on Bugzilla, which involved a bit of Windows Registry jiggery-pokery.
Turns out that it had something to do with a Microsoft Office-related entry messing with the Firefox settings for handling HTML files. Bah!
