I am facing an issue while loading the docking window saved XML to load. I have cross-checked XML files and found that there is no error in xml file. But while loading into an application it will show a red color lock icon.
Secondly, additional empty tabs will be shown along with other tabs. I have attached the screeshot. In screenshot, it has fixed window. But red icon can be seen in docking window also.
There are scenarios where empty tabs will be seen in mid of multiple tabs. But data collection don't have additional records.
