Unfreezing column does not work

I am using unfreezing column as documented and in javascript and it breaks the entire application. Freezing column works perfectly, however unfreezing makes the whole application not function anymore. Any insight into this would be greatly appreciated.

Please share example/demo or a JSFiddle example where I will be able to replicate the issue and change the settings (code access).

I am closing this issue as there is no reply from author for more than a week.
