How to update the project browser?

[Tiemo Hollmann TB]

Hello,

sometimes the project browser doesn't gets updated automatically. E.g. when
ungrouping a group via msg box, the group stays visible in the project
browser until I close and reopen the PB.

Is there something like a "F5" to let the PB update, or is closing and
reopening the common way to handle it?

 

Thanks
