Pirate The World - Online Adventure Game

Sometimes when I move around with the arrow keys it doesn't move my ship but shows an error icon in the browser. After going to the error message I found that it says there is a script error at the start of line 97 which is where the keyboard code starts. The message also says that the wrong data type is going to it so that is something for the programmer to have a look at.

If you could post the error here when it pops up it would help more.

Well the error doesn't show unless you click on the icon when it shows but here is a screen shot I took of it. I use avant browser but the same script error should apply to IE also.

Thanks.
