OE SHOULD remember your last save directory, but there's a bug in the
routine. When you close OE, the last save location is saved to the
Registry, but the last character of the path is cut off. This makes it an
invalid path, so OE defaults to something else.
See
www.kellys-korner-xp.com/xp_tweaks.htm, Line 242, Set the "Save
Attachments" Default in OE. This small utility will provide a work around,
by allowing you to choose your own default location, and pad it, so that
when it gets chopped off by OE, it still resolves as a valid path. If you
find OE suddenly saving to a different location, run it again. Should be
good for about 100 openings and closings of OE.
