Constantly with Skitch's window snap (click snap, then click on a window), it'll mess up with UI elements. Specifically toolbars on apps like Safari, but this time it's a really weird one. Take a look:

Skitch isn't showing the selected message, the username, the direct message icon, and replaced the scrollbar with a white box.

If I take the screenshot again, it'll work fine. So it *does* allow me to take a screenshot of it, but it takes another try which is slightly irritating.

Any idea why Skitch has a hard time capturing toolbars, and other UI elements?
