I like the integration with iCal, but I can't make it work! I highlight a slip to select it, but the option to send to iCal(or Daylight) is greyed out. I've tried opening the slips to see if that helps, but it doesn't. One time I was able to do it, don't know how, and I have a "billings" entry in the calendar. Can't make it happen again though.
How much integration is there? Does the communication go back to Billings if I make changes in iCal (or more likely in Calendar on windows mobile, which I sync via Missing Sync?)
