hi, your avatar says you're using keyclone.

but if not, and i doubt this is the right answer, if you're using aragent's multistep isboxer project (here), but jrob was having trouble with 'jumpy targetting' (here) and as i was having that problem before, i pointed him to the extra ftl assist me in the melee iwt mapped key fixed it for us.

on a probably related note, this macro (isboxer-related) stopped working too:
Code:
/follow {FTL}
/follow [@focus, exists, help]
it was based on ZorbaTheGeek's post here with regards to multimode ftl targeting. i had to change it to "/follow focus" instead and moved it to before /follow {FTL}

so if you're using focus targeting, it's probably related (?). not entirely sure but something's amiss.
