There is no file menu item for loading files and looking at them from your local disk... would be nice, but since none is there, I just dragged and dropped... also typing in C:\.... works, though file:// does not.

When using either c:\... or drag and drop with the 5.5 rendering engine IETester crashes. It works fine with my default IE7 engine and the IE6 engine.

Great tool, I will use this a lot.
