Hi All.

Found an issue on subject. Maybe it’s already known.  
Block list is empty after block edit. After selection of any block the list is back.

I’m not seeing that here.  
Could you please provide your `SystemInfo` data?

If you start from empty file, add geometry and create a block with “+” on the panel, then this new block behaves as I described.

If close Block manager and open it again while have blocks in session - no list dropping.
