Sean, it took me some time to figure out just why I experienced this problem. And I discovered the reason accidentally. I had chosen SIVER as the APPLICATION COLOR SCHEME under SE OPTIONS/HELPERS. In this configuration, the MIN/MAX/CLOSE icons in the upper right hand corner that affect the individual files (not the overall software) are a pale yellow and nearly invisible. When I realized this, I went back and checked my records. I had previously used what is now called (and may've always been called) CLASSIC SILVER. In this scheme, the above icons are clearly visible.
