Column Moving messing up hide/show popup

When I right click on a header to disable or enable a certain column, frequently the column move will override that and bring up a box as if I’m about to move a column. How can I just disable column moving for right clicks (it’s really ridiculous to move a column with right clicks in the first place, that is what left click is for…)

Hopefully a right click will only bring up the hide/show columns menu. Any ideas on how to work around this / disable column moving for right clicks?

Problem confirmed and fixed, updated js file will be sent by email.
The same fix will be added to the next version of the grid ( move column functionality will not react on right clicks )
