Wt

Hi,

I get an Arithmetic exception (division by viewportHeight when it is zero) when running the code attached to the forum thread [1] on a browser (Chrome) with Javascript disabled. I'm using the git version of yesterday (25/01/12).

Stacktrace:

Thread [7] 12988 (Suspended : Signal : SIGFPE:Arithmetic exception)
