In Vault 2020, the Copy Design dialog was upgraded to be separate from the main Vault client. This meant that while the Copy Design dialog was in use, the main client window could be independently used to search for data etc.
I would request that the same treatment be given to the Change State dialog box.
Almost every time I am using the Change State dialog box, I am opening up a second instance of Vault to search for information I need on the parts coming up in the dialog box.
If the main client window was accessible during this dialog box I would not need to open a second client for this purpose.
