Chrome Blanker

[MilesAhead 22]

If you start a chrome based browser using "about:blank" for the start page, you can end up with the caret in the Address Bar in front of "about:blank." This means to type in something new like a url or a search string, you have to hit some keystrokes to get it out of the way.

This little Windows hack automates that.

Run n the tray. Any time it sees a window with Title "about:blank" and text "about:blank" it sends F6, then Delete keys to get rid of it.

This is just an interim kludge. I'm hoping eventually somebody on Chromium team fixes it.

I added a couple of things such as protection against "already running" dialog, about box etc..

Also periodically it calls EmptyWorkingSet() to avoid accumulating memory while sitting in the tray.
