Daniel, thanks for the trick. I tried it and it works in most cases.
Though, it doesn't work reliably when cursor is over Finder windows (*).
Does it match your experience?
[(*) presumably because Finder sets cursor after me or some such --
this happens during drag&drop; to extent I was able to workaround
this by setting my cursor in timer.]
