Hey guys,
https://www.bryntum.com/examples/gantt/advanced/
We're having an issue with the column visibility pop-up (i.e. right click on task list header, and select columns).
Using the advanced demo - adjust your window so it's shorter than the height of the pop-up, then collapse the gantt completely to the right, so you can only see the task list, then right click on the extreme right edge of the task list header to bring up the column selector, and then try to scroll the list - the list closes.
This is less contrived than it sounds in our use case as we have a lot of default columns.
Thanks
Chris
