interact with target spam problem

[CplBob]

I get the same problem. Though it only happens at the start of a fight. It goes a little like this:

I target and hit 'G' which is my FTL/Assist macro then I run up to the mob and hit 'F' which is my keybind for interact with target. At which point occasionaly one or all of my guys (even the current leader I am playing) will start to auto run. So far I stop this by catching it quickly and telling my guys to follow me again. If I dont see it though, things get a little messy

Also to note. I played a day with my alt toons having 'Click to run' set off and I never experienced this problem. Yesterday I had it turned on and it started. Maybe its a bug in the game?
