We just installed 3 purchased copies of Quartus Prime on a lab network. The GUI opens and compiles properly but the "Messages" window does not show anything such as syntax errors, warnings, etc. Is it possible that our installer mis-set a default option?

There's a tab at the bottom of the Messages window, selecting between System and Processing messages. Is it possible you have the wrong one selected? I'v never heard of no messages showing.

Also, at the top, there are options to filter the messages based on type or string matching. Maybe those are modified so nothing matches?
