..so you write about them somewhere, in case you forget them again!
I've just setup a new b0x for work, so there might be a couple of posts like this ;)
The current one is for Visual Studio 2005: Tools \ Options \ Projects and Solutions \ General \ Show output Window when Build Starts
Essentially, when you build, it takes you to the output window so you can see what's happening. I really didn't like it's default behaviour, which sort of feels like nothing is happening (apart from the small text in the statusbar). The setting above lets you see what's happening rather than leaving you sitting there wondering what's going on.
