[Inkscape-user] default directories

WinXP.

I can't figure out how to change the default directories for "save as" and "import" (etc). I've tried to change the "Start in" property of the shortcut, and I've tried writing a small script that starts with "cd ...".

I've looked in preferences.xml, and didn't find anything that looks likely. I also don't see any likely command line options.

So ... how can I change the defaults for these directories? Is it any different in Linux?

Thanks, gary
