I wasn't sure whether to do the 23 things 2.0 thing at all, but I think I've decided that I won't. Instead, I'm going to start documenting the things about Word 2010 that strike me as being almost irredeemably stupid.
The latest one I've found is insert/overtype mode. In all the previous versions of Word for Windows that I can remember, and I think the earliest I've used was 1.1 or 2, you control this by pressing the Insert key. Clearly this isn't good enough for the idiots that designed Word 2010, so it's now disabled by default. You can enable it by going into the advanced settings bit of options, but that only enables it's use for overtype mode - you have to right-click on the status bar and select an option there to get the current mode to display!
There will be more of these irritations in the future!
