Using Mac and Chrome, the Event Viewer has columns off to the right. Not specific to Mac or Chrome. Same behaviour on Windows and Firefox. When the event viewer is in focus, that is, when it is clicked, the only way to scroll right is to use the scroll bar at the bottom of the screen. The trackpad "scroll right" feature does not scroll right.

"horizontal scroll by trackpad ", this feature is not possible with current version, because Event Viewer table use GridX lib, but the GridX library have been out of

maintenance and no feature request can be requested.

For now, user have to click the scroll bar first, then use the trackpad to do horizontal scroll.
