I'm having trouble importing groups in 1.6.12. I checked out the help file on (C:\Program Files\kiwanja.net\FrontlineSMS_1.6.12\help\filemenu.htm) and see Groups listed in the CSV formatting. Indeed if you export the contacts the groups show up. If you delete a contact then import that same file it doesn't tag the new contact with a group.
I'm running the windows version of 1.6.12 on an XP laptop (with a ST860 EDGE MODEM on the Leo network).
This is an screenshot of the groups I've got going. I've also attached a anonomyized/randomized version of the file I'm importing.
Anyone have any thoughts?
