Interesting.

Now that is something I do have: an Nvidea GeForce 260 shoe-box inside 
the i7 computer case which is used to full (RO) capacity: 16MB VRAM. 
That is 2560x1600 x 16M colours.

I wonder if the ghosting is anything to do with that? RO might have 
totally crashed and exitted, but the graphics card has kept the RO 
screen image in its memory and only shows the Windows7 windows when a 
mouse button is pressed?

Could this be what is really happening?

Of course, that doesn't mean that the RO emulator gets off lightly; it 
has crashed irretrievably.

Something similar has occurred on more than 4 occasions here: the RO 
window (originally full-screen) becomes a much smaller and blank 
(white) windows7 window in Windows7 desktop. This too takes TWO 
ALT-ENTERs to recover from. The first ALT-ENTER gives a larger (and 
normal - i'e. it has RO stuff inside it) RO window within the windows7 
desktop.

The second ALT-ENTER puts the RO window full-screen. This is as 
described in my earlier posting under subject heading 'RO's 
full-screen window reduced to blank when iPhone inserted'.

Somethings flakey somewhere.
