I created some check boxes in a document, and the checkboxes randomly disappear for no apparent reason. They will reappear briefly if the document is scrolled, or I mouse to the header, but then disappear again.

The document has a header with a picture, a frame with text in it, and text aligned as a paragraph. The header has a border at the bottom. The body of the document has a table, and a line below it.

I have tried toggling all combinations the View options (Use hardware acceleration, Use anti-aliasing) without success. I have NVIDIA SLI Dual GeForce 8600M GT graphics operating in non-SLI mode, with 2 separate screens, and have updated to the current driver as of 9/21/12. I have created a check box in a blank, generic template, and this behavior does not occur. Any ideas.
