not sure you posted your config correctly, I can not load it into isboxer.

but I do not use follow strobing, caused more problems for me then anything. What I use now is just a follow key that makes all characters follow and assist key to make all toons assist.

also there is an option in jamba to make them auto-follow after combat.

if you can post your whole config to http://pastebin.com/ I can try to help ya further
