I have a fairly fresh install of Windows7 64-bit Enterprise on a new Dell Latitude E6510.
About 2 out of three times upon login to the desktop, the live icons will toggle between the normal document type image, and the live icon document content image. For example, Word, Visio, PDF files on the desktop will display their respecitve application logos, then revert to the live icon image, where the content of each document is represented in the icon. This "toggling" occurs about every two seconds or so.
I can work normally when this happens, but I have to be fast when trying to select something on the Start menu, between the blinks... Including Shut Down, Logoff, and Restart functions - an open Start menu gets closed when the icons toggle.
It seems that a restart does not always clear the issue, but I've found that logging off then back on almost always does.
Anyone see this behaviour before?
