This issue appeared when I first tried to find an element in the dom view....appears to be consistent and frustrating. 
Has anyone else run into this?

Create a simple test as follows. 
Product Version: 2013.1.806.0
IE Version 10
Windows 7 Professional sp1

1. Navigate to google.
2. Create a wait element visible on the "Google Search" element.(Enable hover highlighting on the browser, move over to google search  button(larger part of it) and click on "blue nub" to bring up the elements menu, click on the quick task and select wait - element is visible)
3. Save!
4. Back in Test studio, go to the elements find the newly created element for the verificatoin.
5. Right click and select edit live.
6. In the Find element Screen, click on the DOM tab.
7. Click Validate.(This should expand the DOM tree)
8. On the dom view area, use the bottom sliderbar and slide it to the far right.
9. Click in the DOM view window.
Result: Error!!!! WOOO!
Expected: Not an error.
