Division by zero error occurring in AdvColumnGrid

We are processing data using AdvColumnGrid.

If you drag while touching on the touch screen, division by zero occurs.

The symptoms that do not occur when clicking or dragging with the mouse occur in a PC environment using the touch screen, division by zero occurs.

I can't find it because it doesn't appear as an error.

Changing various things on the property does not solve the problem.

Is this the latest version of the component?
How is this grid setup? Do you refer to column dragging? Row dragging? Cell dragging? Other?
What are the minimal steps, starting from a default grid on the form to reproduce this?
