"Hamish suggested that this may be a generic problem on MS windows
(vista)" might have been better phrasing. Sorry for misinterpreting your
In this particular case, it may be a problem of a 32bit application
running on a 64bit system with more than 3GB RAM, causing rather ugly
out-of-memory errors because the 32bit application requesting more
memory can't handle the memory returned by the OS. Just a wild guess,
maybe a windows developer can say more about it.
