Mysql Workbench Result Grid. Very reliably happens and extremely annoying. I can drag up from the Action Output and see an empty panel display.
Workbench with empty grey panel I am using MySQL workbench 6310 on Mac OS X 10132 17C88. Seen this reported in stackoverflow as well. I no longer have to restart but it is a very stupid state of affairs.
When I query a table in MySQL Workbench no results are shown the result section is just blank no grid or anything.
The following figure shows a single subtab and highlights the main features of the result grid. Workbench running on Win10 connected to DB on RHEL server. Use one exclusively for commands or queries that use the results grid do not mix with other commands used the other connection for those. Seen this reported in stackoverflow as well.
