After what you mentioned about the program minimizing, I went to take a look to see if anything unusual is happening.  Here's what I saw:  When the program opens, the clipboard shows up as normal, but I noticed the quit tab flicker, or look shaded as if it was being hit.  Rolling the cursor over any tabs, on-line, off, H2H, all have no effect - but rolling over quit and it looks shaded, as if depressed.  Also, a single click anywhere on the page will close the program as if you'd hit quit.  
Thanks again....
