Mmh, I'm not really sure and I don't have access to a windows box to test
with. But try setting as your $PAGER 'less -r' instead of 'less'. This might
help, since it may be that the control characters used by ipython for coloring
are confusing less in the default mode. Also, please test by setting '@colors
nocolor' and let me know if the problem remains. This will at least clarify
whether the color escape sequences are causing it.
Also, if any Cygwin user has any suggestions, they'd be more than welcome. My
help for Windows users always tends to fall way short, unfortunately.
