Error list and class hierarchy unexpected refresh

I'm running LabVIEW 2013 Service Pack 1

There is an irritating issue that I am sure I have never come across before, in that the Error list, class hierarchy window, VI hierarchy window, and I am sure other UI elements are refreshing themselves every few seconds.

For example:

Open the class/VI hierarchy window and browse around. In a couple of seconds the pane will refresh its position to hte top left corner.

Ensure that the error window has enough errors and warnings (show warnings is reccommended!) that it shows a scrollbar. Scroll down and sellect/highlight an item (this happens naturally if you ctrl-L from a VI). Scroll up/down the list and in a couple of seconds the list focus will move back to the highlighted item.

This is really, REALLY irritating me with refactoring a large project. Has anyone else seen this, and is it fixable?
