Hi Dave,
not sure what exactly i did yesterday. I think after exporting i clicked [Manage Configurations]. From there i opened Administratons/Projects and deleted a project from there. Then i used the browser back button (Alt+Left) to get back to the Export page.
This might be something not used in this way very often. However the effect is tremendous as it requires a restart of the Continua Service.
Related to the issue here: “Wrong TAB after managing configurations”
It might be a solution to open a new browser page to display the “Manage” page for configurations. This might get rid off the problems mentioned here.
