>Really strange solution. Suggestion was to change display font size from 96 to a higher nomber. I changed resolution to 1024x786 and sixe to 170%.

Just an FYI - We had the same problem, but only with Compaq 7020 flat panel displays, and only when the resolution was set to 800x600. We set the resolution to 1024x768 and the columns showed back up in preview mode.
