retrieving prices takes 0.5 sec to do. the paint just stays until it finds a next task to do.
In your case it is moving the camera since you are using the antiban feature.
So all you ahve explained isn't strange at all, it just normal behaviour.
The only strange issue atm is the walking back and forth. I'll have to take a look on what's goign on with the latest client version.
