Everquest characters running off

My boyfriend is trying to run three instances of everquest and with two characters on auto-follow they tend to run off at the slighest turn and lose control. They seem to have lost their power steering :). Anyway, is winEQ going to help in any way, and if so, how and why? If not, what can he do? He lowered the frame rate to 10 which didn't work. We're going to try WinEQ (we hope that it emulates fullscreen thus not putting the processes in the background) and see if it works -- but if it doesn't, any help would be appreciated. Thanks.

Did he disable or otherwise turn off the passing of movement keys between his main and slaves? I blacklist WASD and use the arrow keys when I need to move slaves independant of autofollow.
