Txt file upload / Data locking

Hi,

We are using the txt file upload functionality in BPS (very similar to the one in the How-to).

If when the pop-up window opens the user decides to close the pop-up box and the web interface without loading anything, the locks are not released and it's causing locking issues to other users.

How can we make sure the locks are released when the user Exit closing the Browser ?

Thanks

David
