This isn't the lag you'd normally expect where your guy seems to hop across the screen and everything around it slows down too. What happens with mine is that when I click on say, a rock. My guy will stand still for a LONG TIME (exaggerated, really like, 20 seconds) then he'll start to move again. Everything else (NPC's, other characters) move around fine, in other words, my character is basically stuck in time.

 

 

 

This happens repeatedly, but only on my laptop. does anyone know why this is happening, or how to fix the problem? (I suspect connection problems)

I wouldn't know the cause yet but it would help if you narrowed it down because there are so many causes for this. First you should try the laptop with it plugged directly in the router with a Ethernet cable to make sure the loss of connection is not created between the router and your computer taking in to consideration that the laptop is the only computer with this prolblem. I assume that your computer has no trouble with the actually running of the applet, just lack/loss of connection.

I have a wireless adapter if it helps.
