JWt

The exception listed at the bottom of this issue description got thrown in specific when scrolling in a WTableView that was displayed in a zoomed out chrome tab.

Further testing showed that:

• the same exception is thrown when the tab is zoomed in
• the exception is not thrown in firefox

This is seems to be caused by the fact that the javascript event arguments passed by chrome are now non-integer values wether they still are for Firefox.

This has been tested only with jWt v3.3.3 but may affect newer versions.
