For some reason IE7 is not displaying some sections of text until I select the area where I know the text is. It then displays all the text that was previously not displayed, as if selecting the text with the cursor has somehow refreshed that part of the page. I am using an external style-sheet.

Also, on scrolling, some text starts to break up with horizontal lines. The only way to get solid text back is to hover over the text with the cursor.

Any ideas?
