RE: Can't open file 'D:\Repositories\repo\db\current': The process cannot access the file because it is being used by another process

Thanks for the suggestions. I must admit, I have a tendency to blame
anti-virus software for most of my problems too. This particular brand
is McAfee - it's already given some trouble on this machine by
preventing dumps of MySQL databases - scanning the C:\WINDOWS\TEMP area
and causing apparently random failures. I will try this out and see if
it helps.

I think that Linux would probably give less trouble overall, but I
don't have control over what OS is used.
