Are you using the version from mqemulator current for your client? sounds like there's a problem with sticklogic, could you by chance post your mq moveutils ini file in text form? Just need to see if there's a problem there.
Also try running MQ2 as admin before you start your EQ clients (later clients, SoF+, can sometimes mess with MQ2 if it's not loaded first) and do a /plugin list when you're in game. Should load somewhere between 9-12 plugins.
EDIT: Are you getting an error in your MQ window on your other clients?
EDIT2: Just a random thought, set your background FPS to minimum, and test it, then set it to 30, test, then max and test. See if that changes anything. If you're using UF client, the background FPS options are totally fubar.
