Haveing the same sort of problems. Running a Palm Treo Pro with windows mobile 6 and recipes appear to sink ok, however, no shopping list. It will partially sync when the shopping list file is manually deleted off the phone, but not the entire list. After that inital load the phone then reports an error and the list is gone. Also the meal plan recipes don't seem to sync just the one selected in bigoven.
First thoughts were a security issue so I checked all the files/folders had permission and double checked activesync to no joy. The Bigoven program is running under administrator mode and it is deffinitly syncing to the right folders as the recipes work.
Window 7 home premium 32bit RTM version
Latest activesync installed.
Bigoven windows and mobile are up to date.
