Summary: Breakpoints Tree Misaligned

Initial Comment:
Sometimes the root node of the breakpoint tree (which 
ordinarily displays a file name) will be drawn above the 
top of the viewport in the Breakpoints tab of the 
DebugPanel.  All you can see is one pixel of the 
expand/collapse knob protruding below the top edge of 
the display.  If you click on that one pixel, this error is 
produced:
