This fixed it for me http://channel9.msdn.com/forums/Coffeehouse/256901-Stop-the-Ding/

I checked in Process Monitor and ccselect is called, then half the hd including a usb stick! is searched for that file. Seems like 30-40 random folders. Ends up in Windows folders with a successful DING.WAV ,stupid.

Notice file name of wanted wav file, weird.

You can just press DEL for the entry you want to ignore/delete. Or use Library tool. But yes they should extend the already awesome bar. Not so sure about search features, there are extensions for this already, but make it more clear how powerful it actually is. Perhaps add a rollover button or 2, giving access to queries/filters (older than 20 days, only show .com for example) Let users tinker with queries (made in library, can already save search queries/results) without making it too complicated. They could start with adding a "how many results to show" in Options. Some might prefer 25 results instead of default 12 or what it is.

Yes, awesomebar/places was the reason for going sqlite. Old dat/html something format was worse! Long lists are not fast and manageable because they are not in sqlite format. You can query all day long in library via commands, there is an extension for this I think, but how many do that? Is 1 out of 1000 interested in Places Query Syntax ? Database can do a lot more than what most see. Sqlite might be overkill if you know all "database" features but is it not almost a standard solution for programmers when they need more than "lists"? Many programs use it or that is my impression.

If sqlite is sqlite regardless of where it is used how to implement must mean a lot. Long time ago I read a database expert freaking out about how Firefox handled places. Make one change and it is like whole database must be reindexed/updated. Why I suffered managing 1000s of bookmarks on old 3.0 version. Hd, whole computer was almost freezing for minutes when you did simple copy/paste functions in bookmark sidebar. That was also powered by sqlite.

History/Places change quite a bit in 4 btw Places got Async Expiration
