One of the developers on XPlanner, Jacques Morel, dropped me a comment on my post about my Pain with XPlanner post:
0.7 is very close (within a month) and has this problem solved.
You can build it right now from subversion. It is rather stable (we release it every 2 weeks internally). I am scheduled to put out a beta anytime now.
So I’m a sucker for personal contact and open source tools, and I don’t really like spending much time in Excel. So it’s on my Backpack todo list for tomorrow, so assuming some fires don’t erupt at work I should be able to pull it down and try again. And of course this will force me to pull down a Windows subversion client at work, probably Tortoise SVN.
