Hello~
Currently we are using dhtmlx.
However, we have found a dhtmlx bug.
Please see the attached files.
① Reduce the size of Windows.
② Drag the grid out of the windows.
③ If get back to the window inside, Move to the grid at the same time on mouse movement.
(After a mouse click Zoom out and then comes out to the outside of the screen grid, the grid moves according to the mouse movement even if you do not have a mouse click)
Request bug fixes.
