[BUG] Desktop app stops showing the details of its work, if I visit to usage and return

What's Wrong?

After I gave a prompt to work and watching the Agents operations, when I leave to check the usage and return, I see only one liner of 'working' or 'writing', but no details about its work. The work around is to start new thread in the next prompt.

What Should Happen?

It should continue to display its actions, as if I haven't left to watch the usage.
