Using EG is like walking on glass shards, so I will not attempt to list all the deep cuts and all the paper cuts one has to continuously deal with. Still, one is annoying and repetitive enough that I must take the time to raise it here:
When deleting a table, one is sometimes told that the table is locked, as seen above.
The table is not visible in the process tree even though it is opened (without being identified) by one of the programs, and the easiest way is then to go back to the process flow view, search for the table somewhere in the flow, delete its shortcut there, and then one can delete the table proper.
Please provide a prompt instead of this ludicrous "unexpected error".
