this was a new image and all I was doing was bringing up the System Browser
I have run Pharo on this old XP SP 3.1 laptop on my writing desk for a few years now ... it was disappointing to encounter, as I am expecting Pharo3 next month and then in April, the next WIndows 8, so I sort of had in mind that this sort of thing was not there ... no method had been changed, nothing had been executed with CTRL-D in a workspace ... strictly the most basic sort of sanity check, and that only because I am not used to just copying down latest.zip
I will look to reproduce now.
