Teleporting (Not Lag)

I have a radion 9800 Pro and i am having really strange problems.

My Brother got me Guild Wars and his works Fine. But when we were playing he noticed that i teleport....i thought it was a glitch in the game but he says his doesnt do it

Problem

I will click somebody or somthing and it will Teleport to it.

I will teleport inside the persons body but it takes a min for me to beable to talk to it.

It is really strange like i dont run when i click on something to attack i just teleport to it and it shows my body inside what i clicked but i cant do anything to it.

Yes, Many threads on this issue.

i searched and only found oen....but there was no answer.
